Transmission Electron Microscope (TEM)

• TEM Sample Preparation in Biological Science

  

  for 95 minutes

  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.

• A Synergy between Cryo-EM and NMR

  

  for 50 minutes

  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.

• Electron Probe Microanalysis - Presenting the latest generation of JEOL microprobes opening up new frontiers

  

  for 67 minutes

  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.

Mass Spectrometers (MS)

• A New Proposal for Copolymer Analysis -Multifaceted Analysis by High-Resolution Mass Spectrometry and NMR-

  

  for 31 minutes

  Many synthetic polymeric materials utilize copolymers composed of two or more monomers. Because their structures are more complex than homopolymers, the information that can be obtained with a single analytical instrument is limited. In this seminar, we will introduce comprehensive structural analysis methods that utilize information obtained from various methods such as NMR, GC-TOFMS, MALDI-TOFMS, and TDP-DART-TOFMS.

• 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-

  

  for 30 minutes

  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.

• How to get the most out of High-Resolution GC-MS

  

  for 60 minutes

  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

  

  for 60 minutes

  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. It will be shown that not only screening but also precise quantitative analysis can be done in 15 minutes with a Fast GC condition for around 300 pesticide residues in food samples.

• A Practical Introduction to Diffusion-Ordered Spectroscopy

  

  for 68 minutes

  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

  

  for 61 minutes

  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

  

  for 39 minutes

  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.

• Elucidating nano-crystalline structure by combining microED and solid-state NMR

  

  for 57 minutes

  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

  

  for 62 minutes

  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

  

  for 58 minutes

  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.

  for 60 minutes

  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.
