Powerful Separation and High Resolution Mass Spectra

AccuTOF™ GCxGC Mass Spectrometer - Powerful Separation and High Resolution Mass Spectra

Powerful Separation and High Resolution Mass Spectra

In combination with comprehensive 2D gas chromatography (GCxGC) using the Zoex thermal modulator, the AccuTOF™ GCxGC Time-of-Flight Mass Spectrometer offers both powerful chromatographic separation and high-resolution mass spectra. The AccuTOF-GCxGC also offers a variety of ion sources and features an Instrument Detection Limit (IDL) of 16 fg, statistically calculated from repeated injections of 100 fg octafluoronaphthalene (OFN).

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-GCxGC 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.

High Sensitivity GC/MS with high speed acquisition and high resolution

The AccuTOF-GCxGC is one of the most advanced mass spectrometer systems of the AccuTOF™ GC series of gas chromatography/time-of-flight mass spectrometer systems. You can find out here how the AccuTOF GCx technology works.

Reliable determination of elemental composition

The high-resolution and high mass accuracy AccuTOF™ GCxGC enables accurate elemental composition determination, which is a powerful tool for the qualitative analysis of unknown compounds and impurities.

Multiple ionization methods

The AccuTOF-GCxGC 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.

Standard: Electron Ionization (EI)
Optional: Chemical Ionization (CI)
  Field Desorption (FD)
  Field Ionization (FI)
  Combination EI/FI/FD
  Photoionization (PI)

Automated performance optimization

Automatic ion source tuning, drift calibration, data file conversion and export optimize the speed and performance of the AccuTOF-GCxGC.

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-GCxGC 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.

Key Features

  • Allows multiple analytical techniques without breaking vacuum
  • Simplified direct sample injection
  • Optional EI/FI/FD combination ion source allows for GC/EI, GC/FI, and FD analysis without source change
  • High data recording speed
  • High sensitivity, resolution, and mass accuracy
  • Stability from run to run
