High Sensitivity GC/MS with high speed acquisition and high resolution
The AccuTOF-GCx-plus is the most advanced mass spectrometer system of the AccuTOF™ GC series of gas chromatography/time-of-flight mass spectrometer systems.
Reliable determination of elemental composition
The high-resolution and high mass accuracy AccuTOF™ GCx-plus enables accurate elemental composition determination, which is a powerful tool for the qualitative analysis of unknown compounds and impurities.
Powerful Separation and High Resolution Mass Spectra
The AccuTOF-GCX-plus offers a variety of ion sources and direct probes and features an Instrument Detection Limit (IDL) of 16 fg, statistically calculated from repeated injections of 100 fg octafluoronaphthalene (OFN). In combination with comprehensive 2D gas chromatography (GCxGC) using the Zoex thermal modulator, the GCx offers both powerful chromatographic separation and high-resolution mass spectra.
High resolution and mass accuracy allow for rapid elemental composition determination and target compound identification. With a fast analog-to-digital converter providing high linear dynamic range, the JEOL AccuTOF-GCx is perfectly suited to analyzing complex mixtures of true unknowns — even at low concentrations. Applications include: environmental, petroleum, polymers and materials, forensics, foods, flavors, and fragrances.
Powerful, streamlined data analysis
While hundreds or even thousands of components can be separated and detected using this type of system, interpreting the data sets can be challenging due to the unprecedented amount of information the data provides. The AccuTOF-GCx features new software methods and tools to simplify the analysis of GCxGC/HRMS data sets from complex mixtures such as crude oil and environmental contaminants.
Multiple ionization methods
The AccuTOF-GCx-plus is designed for optimum throughput, operation, and uptime. An optional combination EI/FI/FD ion source eliminates the need for source exchange for these experiments. Gas chromatography/field ionization can also be used to characterize samples that would be difficult to analyze by any other technique.

Automated performance optimization
Automatic ion source tuning, drift calibration, data file conversion and export optimize the speed and performance of the AccuTOF-GCx-plus.
Compact footprint
An integrated chassis consolidates all requisite spectrometer components, including vacuum pumps, into a compact footprint. Temperature-sensitive components remain under controlled conditions and overall instrument stability and experimental reproducibility are greatly enhanced. The AccuTOF-GCx-plus is also uniquely designed to remove 99% of He carrier gas ions before they enter the flight tube. Since the bulk of the carrier gas ions never reach the detector, the MCP lifetime is maximized.
