Wide Dynamic Range - responding to a wide range of sample concentrations
When concentration difference of measuring materials contained in a sample is large, in some cases, changing the measurement conditions is required depending on the concentration difference.
The JMS-Q1050GC equipped proudly with a largest sized hyperbolic-shaped quadrupole in this class has a large allowance in ion, as a result accomplishing a wide dynamic range for the amount of ions
This capability enables you to measure a sample without changing the measurement conditions depending on the concentration of a measuring material in the sample, manifesting its analysis power for a sample with a large concentration difference.
In addition, the hyperbolic-shaped quadrupole has superb ion transmittivity, realizing enhanced sensitivity especially in high mass region. Furthermore, by controlling the temperature of the quadrupole unit with high precision, the m/z axis stability has been remarkably enhanced.
High Sensitivity - stable for a long period of time
Flowing a large amount of carrier gas in the detector causes an increase of noise, resulting in the degradation of sensitivity. Therefore, by introducing a newly developed technology (Draw-in lens) in the detector section of the JMS-Q1050GC, we have realized to make the detector highly sensitive with the noise reduced to the limit.
Furthermore, adopting a new filament has realized to make the filament life longer, thereby succeeding in reducing the running cost. In addition, adopting a dual filament structure makes it possible to minimize the instrument downtime and to maintain the instrument at high sensitivity for a long period.
The JMS-Q1050GC capable of introducing a large amount of ions in the quadrupole at a time owing to the large sized quadrupole is one of the technologies that have made a highly sensitive analysis possible.
High Evacuation Performance - enabling analysis under severe acquisition conditions
Exploiting its power in gas analyses
The JMS-Q1050GC is only a GCQMS that can directly attach a packed column used widely in gas analyses.
When you use a packed column, you can analyze noble gas components contained in the air at ppb order at high sensitivity.

A large volume injection analysis is possible
In the GC-MS analysis of a general sample solution, a giant peak originated from the solvent appears after the injection. On this occasion, conducting the measurement gives a large load to the QMS, so normally, the filament is not lit when eluting the solvent.
However, in some cases, a target compound peak is near or overlapped with this solvent peak (see the right figure); in such a case, you need to light the filament just after the injection to continue the measurement while the solvent peak is eluting.
In order to make such an analysis, it becomes necessary to provide a high evacuation system that does not cause shutdown due to a large amount of solvent injection and a quadrupole that does not quench even if a large amount of ions. If you use the JMS-Q1050GC, you can measure a sample under such severe conditions.

Responding also to a double column
The JMS-Q1050GC can analyze a sample using a double column that connects two columns simultaneously to the QMS without adding options such as replacing the turbomolecular pump. Adopting a large split-flow turbo-molecular pump and differentially pumping between the ion section and analysis section suppress the degradation of vacuum in the analysis section even when analyzing the sample using the double column.
Maintainability - fast and easy
Reduced instrument maintenance time
By adding further improvements to the simple structured ion source which has been well established ever since, you need no tools when attaching or detaching the ion source chamber even if the dual filament is installed in the instrument. You can clean the ion source chamber, which will be most contaminated by the analysis of multiple samples, in a short time. Since the structure of the ion source is simple, you need not worry to make a mistake in reassembling the ion source.
Indication of the replacement period of consumable parts
A recording notebook is not necessary. As the software records the use status of consumable parts, the software automatically makes you know the replacement period of consumable parts such as a septum and a glass insert.
Escrime™ - enabling to analyze a multi-component sample at one time.
Passing the qualitative analysis information to the quantitative analysis conditions by one click
You can paste the information of a compound obtained by the qualitative analysis to the quantitative analysis conditions by drag & drop. This function reduces the labor for creating the quantitative analysis conditions, realizing a comfort quantitative analysis with less stress.
Prediction function of retention time
Abundant report creation functions
Not only the number of templates of report is rich, but also the customer can edit the template in any desired form.
Measurement data of 150 or more sample data can be processed in one time
You can, of course, automatically perform peak area calculation, calibration curve creation and quantitative value calculation, in addition to the individual and unanimous modification of the peak area calculation range after that, enabling you to drastically shorten the time required in the quantitative analysis calculation processing.
You can display the component peaks contained in multiple samples or multiple peaks in one sample on the same window.
Furthermore, you can change the calculation range of peak area, and can process even 150 or more samples in one time.
Extensive GC-MS Solutions - proposing a broad range of systems
Next generation HG-GC-MS system
The S-trap Head Space System equipped with trap mode in addition to the conventional sample loop method has realized ultra-low concentration measurement. It has realized to measure mold odor in water, which was difficult using the conventional sample loop method, by ensuring to detect it down to 1 ppt; it is used in the measurement of volatile components included in various substances such as food, aroma chemical, and material.
Sniffing GC-MS System
The Sniffing GC-MS is a method of splitting the outlet of the capillary to lead one channel to MS and the other channel to the outside of GC to directly sniff odor with your nose. The original software AROMAVOICE provided with a high voice recognition function in this method can precisely perform the qualitative analysis of “odor” components.
Combi PAL GC-MS System
The Combi PAL is a multifunctional auto sampler capable of performing the liquid injection, HS, SPME (solid phase microextraction), automation of solid phase extraction, divided injection of liquid sample, dilution, and so forth by one unit.
In addition, using the large amount injection Lavi- Stoma enables you to accomplish remarkable sensitivity enhancement of an ultra-low concentration sample, omission of condensation work, minimization of the collected sample amount, and derivatization.
Py-GC-MS System
The Pyrolytic Decomposition GC-MS System is an analysis method for combining the thermal extraction and pyrolytic decomposition by Multi-Shot Bioanalyzer and GC-MS. You can select an analysis method from instant pyrolytic decomposition, generated gas analysis and heart-cut analysis according to the analysis purpose.
Thermal Desorption System
Because the TD-4J Thermal Desorption System can perform a simple sample introduction without using a transfer line, it can minimize sample adsorption and decomposition. You can apply it, of course, to VOCs in the general atmosphere, also to material analysis, etc. As the basic configuration is single tube handling, it can be introduced at a relatively low cost, making it possible to respond to the automization up to 20 samples using an option.
