GC-MS: JMS-T200GC AccuTOF™ GCx-plus High Performance Gas Chromatograph – Time-of-Flight Mass Spectrometer
DISCONTINUED
High throughput analysis results offered by a new automatic analysis system
The AccuTOF™ GCx-plus is the most advanced mass spectrometer system of the AccuTOF™ GC series products.
The AccuTOF™ GCx-plus provides solutions in a variety of applications.
Features
The JMS-T200GC AccuTOF™ GCx-plus GC-TOFMS is a high-end GC-MS system, which achieves high mass resolution, high mass accuracy, high sensitivity, fast data acquisition, and wide mass range.
A new automatic analysis system provides high-throughput, high-accuracy qualitative analysis solutions.
Three key technologies for achieving automatic qualitative analysis
Three new functions are incorporated in the new GC-MS system, which allows high-accuracy qualitative results to be obtained by anyone.
Technology 1: Integrated analysis of GC/EI data and soft ionization data
The new automatic analysis software “msFineAnalysis” conducts five kinds of qualitative analyses that combine GC/EI data and soft ionization data (CI, FI, PI).
Library search
Molecular ion search
Accurate mass analysis
Isotope pattern analysis
EI fragment ion analysis
By presetting "m/z" value used for drift correction and timing to introduce the internal standard sample, drift correction is automatically implemented after measurement. Since the measured data are already subjected to drift correction, these data are immediately analyzed by “msFineAnalysis” software.

Technology 2: Reservoir Automatic ON/OFF function
Reservoir Automatic ON/OFF
Valve control can be made through the software.
The timing to introduce the internal standard sample, aimed at mass calibration (drift correction), can be set flexibly.
Technology 3: Drift correction multiplier
Multi-point correction using a drift correction multiplier achieves high mass accuracy. This drift correction multiplier can be linked to the Reservoir Automatic ON/OFF function.
This automatic system provides higher accuracy GC-MS qualitative analysis results than the results obtained only from library search. The system offers both shortened data analysis time and superbly high accuracy analysis results.
Various soft ionization techniques and direct analysis to support qualitative analysis
The AccuTOF™ GCx-plus accommodates various soft ionization techniques, as well as Electron Ionization (EI).
These soft ionization techniques are also effective for the integrated analysis using “msFineAnalysis” software.
Two combination ionsources enable quick switching between EI and soft ionization without degrading the vacuum in the chamber.
In addition, the AccuTOF™ GCx-plus allows for analysis with direct techniques including Direct Exposure Probe (DEP), Direct Insertion Probe (DIP) and Field Desorption (FD). The system also supports direct sample inlets for analysis of low volatile compounds and high boiling-point compounds.

Fast data acquisition for GCxGC-TOFMS analysis
High speed data acquisition speed, up to 50 spectra/sec, is suitable for GCxGC-TOFMS analysis that provides ultrahigh separation data. This GCxGC analysis can also be made with soft ionization. Ultrahigh separation analysis offered by GCxGC is effective for analyzing complex-mixed compounds measurement.
Easy linkage to various pre-treatment equipment
The AccuTOF™ GCx-plus enables analysis by combinations with various pre-treatment equipment, like the JMS-Q1500GC (GC-QMS) does.
Thus, its applications extend by the combinations with Head space method, SPME method, Pyrogenic method, and Thermogravimetry.
High basic performance
High sensitivity
Trace amount of components can be analyzed qualitatively and quantitatively.
Octafluoronaphthalene (OFN) 100 fg was continuously measured (8 cycles) by EI method and EIC (m/z 271.9867) was acquired. Based on the repetition accuracy of the obtained peak area of this EIC, statistical calculation was conducted for the instrument detecting lower limit (IDL) by assuming certain reliability, resulting in 16 fg of IDL.

Superposition and reproducibility of EIC for OFN data
High mass accuracy
Accurate mass analysis of the detected ions enables the chemical formula of ion to be obtained.
Mass accuracy of the measured sample with different concentrations
Stability over long periods of time
High resolution
The system allows for separation of adjacent mass peaks with a few 10 mm Da.
Figure below shows that four kinds of ions having the same integer mass of 28 Da are clearly separated and detected owing to high resolution of the system. With a low resolution system, these ions are not separated and detected and thus, the observed mass peak is only one, leading to non-accurate acquisition of elemental composition and intensity (quantitative value).
The AccuTOF™ GCx-plus enables accurate qualitative and quantitative analyses by separating adjacent mass peaks with a few 10 mm Da.

Fast data acquisition
The system supports GCxGC analysis and Fast GC analysis with a high speed data acquisition up to 50 spectra/sec.

Wide mass range
The AccuTOF™ GCx-plus has a wide mass range and incorporates various direct sample-inlet techniques, thus allowing for measurement of samples with large molecular weight, which cannot be introduced by GC.

Dynamic range
The AccuTOF™ GCx-plus has a wide mass range up to 4 orders of magnitudes, thus the system fully supports quantitative analysis as a GC-MS.
