Highest sensitivity GC/MS with high speed acquisition and high resolution
The AccuTOF-GCv 4G features the highest sensitivity (S/N >100 at OFN 1 pg/µL) of any time-of-flight Gas Chromatography Mass Spectrometer commercially available. High resolution and mass accuracy allow for rapid elemental composition determination and target compound identification. The AccuTOF-GCv 4G combines high-speed acquisition of 50 averaged spectra per second with high mass resolving power of 8000 FWHM and mass accuracy of 4 ppm or better to deliver high-resolution, accurate mass spectra with full mass range sensitivity for both qualitative and quantitative analysis. With a fast analog-to-digital converter providing high linear dynamic range, the JEOL AccuTOF-GCv 4G 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.
Multiple ionization methods
The AccuTOF-GCv 4G 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-GCv 4G.
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-GCv 4G 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.
