Time-of-flight mass spectrometer for GC and GC×GC

We have been so impressed with BenchTOF that we have now bought another one...

Prof. Steve Rowland, University of Plymouth, UK

Who used BenchTOF-HD?

Analysts in high-throughput or QA/QC laboratories rely on BenchTOF-HD for its outstanding performance across a wide range of GC and GC×GC applications


Product benefits

  • Cut down on analysis time by detecting trace-level targets and unknowns in a single run.

  • Meet the demands of applications requiring ultra-low detection limits.

  • Enjoy confident chemical identification using reference-quality spectra.

  • Expand your laboratory’s capability by using sub-unit mass selectivity to improve detection of trace-level compounds in complex matrices.

  • Speed up analysis of complex samples with fast GC and GC×GC.

  • Improve your productivity through the greatly reduced need for cleaning or maintenance of BenchTOF.

  • Streamline your instrument control, method development and data analysis with TOF-DS software.

  • Speed up data processing using the near-real-time capability of TOF-DS.
BAT required a novel instrumental capability for the separation, identification and semi-quantification of volatile organic compounds in complex aerosols at very low concentrations. After reviewing a number of commercially available instruments, BAT considered the Markes BenchTOF in combination with Thermal Desorption sampling. BAT was satisfied with the initial evaluations, leading BAT to purchase a Markes BenchTOF in 2012. BAT worked closely with Markes over a number of months to successfully optimise the application and since this first deployment, BAT has purchased two additional BenchTOFs to increase the capacity in this key area of research.

Instrument detection limit

  • Powerful TOF-DS software for instrument control and data analysis, including near-real-time processing, unlockable parameters for fast method development, and ChromCompare chromatographic screening.

  • SIM-like sensitivity for trace-level analysis of targets and unknowns in a single run.

  • Extended mass range (m/z 1–1500) and temperature performance for tackling the most demanding applications.

  • Reference-quality ‘classical’ spectra matching those in commercial or custom quadrupole-acquired libraries.

  • Sub-unit mass selectivity to eliminate matrix interferences and improve signal-to-noise ratios.

  • High-speed spectral acquisition ensuring compatibility with GC and GC×GC.

  • Long-term stability of analyte response for reduced downtime.
