TEM Sample Preparation in Biological Science
There are many ways to prepare biomaterials and at times it may be relatively challenging as it needs experience and occasionally requires specialized equipment.
Biomaterials can be categorized as particles, cells and tissues. Examples of particles are virus, protein, microtubule or bacteria etc. These samples can be prepared with the negative staining technique. Users can observe the morphology (shape, size and structure) and the distribution of the particles. If more details or higher resolution are required, the user can choose to utilize freeze plunging technique.
As for cells and tissue, the samples are generally thick (>10µm), so we have to perform sectioning to produce an ultra-thin section (100nm or less). These samples have to be embedded into the resin block and sectioned using the ultramicrotome. When a good section is obtained, the user can observe the clear morphology of the organelle and ultrastructure. Cryo-sectioning is not required unless user needs to preserve the original hydrated structure and prevent artefacts which may arise from other techniques.
Sample preparations for biomaterial in TEM is very important to reveal the true information of sample.

Electron Probe Microanalysis - Presenting the latest generation of JEOL microprobes opening up new frontiers
EPMA history goes back to the late 50s, but today we witness revolutionary technological developments, that bring in new possibilities, reshape and extend our agenda. More emphasis is now put on low voltage analysis, which in combination with Schottky Field Emission Gun (FEG) performance allows to significantly enhance spatial resolution of EPMA bringing it to the nanometer range. JEOL SXES family of detectors allows analysis of very soft x-rays and chemical state of elements with excellent spectral resolution (0.3 eV) opening new analytical possibilities for industry and research. While the gap in application ranges of EPMA and high-resolution SEM is closing, it is important to emphasise that two classes of instruments are complementing rather than replacing each other. EPMA requires from operators additional knowledge and skills in choosing and setting up analytical procedures as well as for interpretation of results. Thus, another important trend in EPMA leads to development of software assisted analysis and to automation of results processing, which is significantly simplifying operator’s task and allowing to extend user base of EPMA. JEOL is working hard on creating an ecosystem of devices including, but not limited to EPMA, SEM, and XRF - approach improving analytical efficiency and quality.

Automated structural analysis for the real unknown compounds by combining an artificial intelligence (AI) technology and GC-TOFMS system -Introduction of msFineAnalysis AI, an integrated qualitative analysis software-
Electron ionization (EI) is the most popular method used in gas chromatography-mass spectrometry (GC-MS). The compounds are identified by mass spectral database search using EI mass spectra. Because the molecular ions are often weak or absent in EI mass spectra, identification of unknowns can be difficult by EI alone. When this happens, soft ionization is very helpful for obtaining and identifying the molecular ions. In 2018, we have launched an integrated qualitative analysis software “msFineAnalysis” which can combine and interpret the information from EI and soft ionization data automatically.
This year, we have newly developed automated structure analysis functionality on the msFineAnalysis using with an artificial intelligence (AI) technology to predict EI mass spectrum from chemical structure. The newly developed AI model is using a set of actual EI mass spectra and chemical structures over 300,000 compounds. We have already created a predicted EI mass spectra database for around 100 million compounds using with this developed AI model.
JEOL GC-TOFMS system only can offer automated structural analysis results combining with integrated qualitative analysis results and the AI predicted EI mass spectra database.Date:Tue, 4 Oct, 2022

These methods will be illustrated with the composition analysis of UV-curable resins, tracking analysis of epoxy curing, and other examples. In the section of compositional analysis of UV-curable resin, the importance of separation for MS analysis will be explained. By using GPC fractionation, the structures of the monomer, photo-initiator, reactive oligomer, and polymer, which were difficult to identify by bulk analysis, were clearly identified. In the section of tracking analysis of epoxy curing, the effectivity of a KMD plot will be presented. Generally, a KMD plot is used for the analysis of the polymer terminal group.

GC-MS Qualitative Analysis Solution - How can we identify unknown compounds?
Electron ionization (EI) is the most popular method used in gas chromatography-mass spectrometry (GC-MS).
Because the molecular ions are often weak or absent in EI mass spectra, identification of unknowns can be difficult by EI alone. When this happens, soft ionization (SI) is helpful for obtaining and identifying the molecular ions.
Recently we have developed an integrated qualitative analysis workflow to combine and interpret the information from EI and SI data. In this seminar, we will explain the integrated qualitative analysis workflow and its application which we have applied this workflow to polymer samples in order to evaluate known and un-known compound analysis.

How to get the most out of High-Resolution GC-MS
Gas Chromatography-Mass Spectrometry (GC-MS) is widely used to separate compounds in complex mixtures, and analytes are typically identified through library database searches. This sounds like a very straightforward process in principle, but in practice compound identification can be complicated by having multiple high-scoring database matches or low-scoring matches for coeluting peaks. Furthermore, many compounds may not be registered in the database. Therefore, new analytical techniques are needed that make use of the information from high-resolution measurements and soft ionization methods.
In this presentation, we will discuss a new GC-MS analysis workflow that uses high resolution MS in combination with EI and soft ionization methods. The data interpretation software automatically generates a color-coded qualitative analysis report for all analytes present in the sample. The new workflow consists of chromatographic peak deconvolution followed by database matching, elemental composition determination for the molecular ion, isotope pattern matching, and EI fragment accurate mass analysis to identify the most likely candidate for compounds registered in the databases. This information can also facilitate the identification of compounds that are not in the database. A variety of samples will be presented to demonstrate the effectiveness of this new workflow.

GC-MS/MS Quantitative Analysis Solution for Pesticides Residues
A high throughput GC-triple quadrupole mass spectrometer (JMS-TQ4000GC) has a capability of detecting 1000 different ions in a second during quantitative measurements.
The high throughput is useful for measurements of pesticide residues where a large number of samples are handled. Fast GC conditions are known to reduce measurement time, however, they lead to a decrease in sensitivity. JMS-TQ4000GC achieves enough sensitivity and reproducibility even with Fast GC conditions because of patented short collision cell technologies. In this web seminar, we will introduce features of JMS-TQ4000GC based on the short collision cell and application of pesticide analysis.

A Practical Introduction to Diffusion-Ordered Spectroscopy
Diffusion-ordered spectroscopy (DOSY) is a very powerful NMR method for mixture analysis. Unlike traditional chromatography-based methods, DOSY does not perform physical separation of the different components in a mixture; instead, different chemical species in a sample are resolved based on their differing diffusion coefficients. DOSY has found a wide variety of applications, including probing molecular interactions (e.g. aggregation, binding), signal suppression, droplet sizing and characterizing macromolecules.
In this webinar, the basic principles of DOSY will be introduced along with some practical advice on setting up DOSY experiments and basic data processing. The workshop is ideal for practitioners of NMR for want to learn the basics of DOSY, researchers looking to expand their NMR knowledge, or anyone working in the area of mixture analysis who wants to find out if DOSY can help them solve their problems.

NMR Crystallography of Dynamically Disordered Solid
Disorder is a common cause of diversity of solids. Unambiguous determination of a molecular structure by X-ray diffraction (XRD) analysis has been central to many achievements in chemistry and biology, but there are limitations to this technique. A well-known limitation of diffraction experiments is that they typically require a highly ordered crystalline sample and are inherently limited in the structural characterization of disordered samples. As an alternative to XRD, solid-state nuclear magnetic resonance (SS-NMR) spectroscopy is regularly applied to obtain atomic-level insights into the structure and dynamics of solids. In this webinar, several recent examples of SS-NMR studies of disordered solids will be discussed, such as investigation of mechanochemically prepared 2D and 3D arrays of molecular machines or investigation of temperature-induced salt-to-cocrystal transformation of pharmaceutical solids.

Selective Excitation of Overlapping Multiplets
2D NMR can provide a wealth of structural information, but often at the expense of long measurement times. It is frequently the case that a particular structural problem can be solved by identifying just a few correlations between protons. Consequently, selective 1D variants of some 2D experiments, most notably NOESY and TOCSY, have grown in popularity because they are able to provide the required information in a fraction of the time. Unfortunately, these selective 1D experiments are often limited in their application when there is extensive signal overlap, which is frequently the case in proton spectra.

Your data in JASON: file formats and external access
Recently we have introduced new JEOL NMR processing software: JASON.
One of the JASON concepts is focused on the accessibility of JASON data for various applications and analyses. JASON is multi-vendor software that can handle natively most common (NMR) data formats.
But it also organizes its data internally in hierarchical structures which can be stored in common container formats like HDF5. This opens possibilities for the data exchange between JASON and external applications and the integration of external tools into JASON.
A general overview of JASON data structures and application examples will be discussed.

Introduction to solid-state MAS NMR
Solid-state NMR is an attractive tool to elucidate structures and dynamics of solids at an atomic level. Unlike diffraction-based methods, solid-state NMR doesn't require long-range periodic structures, thus is able to analyze virtually all the solids including amorphous, glass, mixtures, micro-crystals, etc.
In this webinar, we will introduce a set of building blocks of solid-state NMR to understand basics: MAS(magic angle spinning), CP(cross polarization), 1H decoupling. Several typical applications will be introduced to demonstrate the capability of solid-state NMR. Lastly, practical tips in solid-state NMR like sample packing etc. will be discussed.

Solid-State NMR Tutorial: Sample Packing, Standard Samples & Sample Spinning
Magic Angle Spinning (MAS) is the basic technique used in solid-state NMR and requires that samples be spun at high spin rates. Proper execution of MAS experiments requires that the sample be packed in the rotor properly, as improper sample packing may result in serious damage to the rotor and/or NMR probe. In this webinar, we discuss the practical aspects of sample packing and sample spinning. In addition, we also introduce standard samples frequently used to adjust the magic angle, resolution, and cross-polarization (CP) of various nuclei.

A Synergy between Cryo-EM and NMR
In this webinar, the aim is to explore molecular structures using Cryo-TEM, starting from a description of the Cryo-TEM technique and how it is used to investigate biological samples in order to scientifically contribute to protein studies. The webinar will also use application results to show how Cryo-TEM can provide synergy with NMR.
Cryo-TEM is a high resolution imaging technique that is used to create 3 Dimensional reconstructions of biological protein structures down to the molecular level. These 3D reconstructions are used to visually verify the positions and configuration of molecules in the specimen and identify different conformational states of the proteins as provided in solution. These results readily provide the information required to complement NMR studies.Organizer: JEOL (U.K.) Ltd.

NMR application in battery research
Lithium ion batteries (LIBs), a crucially important power source, are increasingly demanded for application to electrical devices and electric vehicles. NMR is one of the few analytical methods that can directly observe Li ions and is a powerful tool for characterizing local structure and ion dynamics of LIB materials.
In this webinar, we will introduce NMR applications for each component of LIB such as cathode, anode and electrolyte. Various NMR techniques will be introduced such as solid-state NMR, in-situ NMR, and diffusion NMR because suitable techniques are depending on the materials to be analysed.

Elucidating nano-crystalline structure by combining microED and solid-state NMR
In this webinar, we will introduce a novel method to solve a crystalline structure from nano- to micro-sized crystals. Quite recently, microED is introduced to solve the structure from such a tiny single crystal. Although microED is a very powerful technique, the structure solved by microED is not perfect especially atomic resolution structures. For example, microED often mis-assign atoms with close atomic numbers (like carbon, nitrogen and oxygen) and more importantly locates hydrogen poorly. On the other hand, solid-state NMR is very sensitive technic to probe a local structure. Solid-state NMR has a very high capability to resolve nuclei, and directly monitor 1H. In this regard, information from microED and solid-state NMR provide complementary.
We will demonstrate the combined method of microED and solid-state NMR on a small amino acid and small pharmaceutical molecule whose structure has not been solved. We will also introduce a toolbox for pharmaceutical applications.

Core principles of precise qNMR – Common Pitfalls and Solutions
A modern NMR spectrometer has the exquisite property that the data is inherently quantitative. By following a few experimental guidelines, good accuracy and precision are routinely obtainable. Though quantification by NMR is most commonly done using proton, in principal many spin ½ nuclei could also be used. A unique aspect of quantification using NMR is that typically no chemistry needs to be done up front on the molecule and response factors do not need to be cataloged – Simply put the analyte into solution and record the results. Therefore, qNMR is a non-destructive analytical technique.
The approach to quantitative analysis with qNMR data depends upon how precise an answer is needed. Experimental details also become more critical as higher sub-percent accuracy is required. If an accuracy of a few percent are sufficient for the problem at hand not much is needed except a routine spectrum and a result from a similar sample of know concentration as an external reference. There are many software tools to allow results for either traditional integration or direct time-domain amplitude extraction such as CRAFT which virtually eliminate operator bias or skill from the all-important data analysis part or the qNMR process.

An Introduction to Pure Shift NMR
NMR is an enormously powerful analytical technique, yielding unrivalled insights into the chemical structure and dynamics of organic molecules. Unfortunately, the information that can be readily extracted from the NMR spectrum is sometimes limited by overlap between neighboring peaks, a problem which is often exacerbated by the presence of broad peak “multiplets” due to J-splittings. This is particularly a problem in proton spectra, where the narrow chemical shift range and manifold J-couplings between protons can lead to severe peak overlap. In recent years, much work has been done to develop NMR methods that yield spectra where the peak multiplet structure is completely suppressed; these so-called “pure shift” spectra show much higher resolution than conventional spectra. In this short webinar, we introduce the basic principles of pure shift NMR and describe some of the most popular and important pure shift methods that have been developed to date.

Speeding up NMR: NUS and NOAH
2D and higher dimensionality NMR experiments may require a substantial amount of time to acquire. Non Uniform Sampling (NUS) enables the acquisition of an NMR spectrum in a shorter amount of time by skipping a fraction of the data that would normally be acquired. NUS will be explained and illustrated with a few examples on how it should be used. NOAH (NMR by Ordered Acquisition using 1H-detection) experiments allow acquiring several datasets at the same time. The combination of both NUS and NOAH will be explored in JEOL systems.

NMR without deuterated solvents – principles and applications of No-D NMR
Most users of nuclear magnetic resonance (NMR) instruments tend to dissolve their samples in deuterated analogues of common solvents like chloroform, acetone, or dimethyl sulfoxide. However, there are many applications, like reaction monitoring, where using a deuterated solvent is not actually necessary.
This webinar will review why deuterated solvents are used in NMR applications in the first place, discuss how one can perform the same actions without deuterium, and show practical examples of Non-Deuterated (No-D) NMR.

Advances in Liquid Nitrogen Cold Probe Technology
Cold probe technology offers significant sensitivity enhancements over traditional room temperature probes. Using liquid nitrogen as the cryogen affords greatly reduced operational costs compared to Helium cryostat probes. Another excellent choice with low running costs and slightly better performance is a closed cycle Helium cooler running at 50 kelvin. Basically by reducing thermal noise these probes can reduce experiment time by a factor of about 9 with no loss of experiment flexibility.
Examples of very modern 1 and 2 dimensional NMR data acquired with a fully broadband nitrogen cooled probe will be presented and by example illustrate robust approaches to solving common difficult and interesting strucure problems. Measurements tradiionally difficult to access such as carbon-carbon direct and long-range coupling pathways and J values, now very useful in computational chemistry, are shown to be easily accessible by simple 1 dimensional experiments.
