BenchTOF Time-of-Flight (TOF) Mass Spectrometer from Markes International Ltd


BenchTOF-HD and BenchTOF-Select time-of-flight mass spectrometers for GC and GC×GC

The BenchTOF range of time-of-flight mass spectrometers connect to any GC and offer major sensitivity and productivity advantages for a broad range of GC applications.

Designed from first principles for optimum performance, BenchTOF instruments equip GC–MS laboratories to meet the demands of increasingly complex applications, and so significantly extend the range of services they offer.


Offering better sensitivity than quad-SIM with full reference-quality spectra, the exceptional analytical performance of BenchTOF-HD is complemented by the outstanding productivity enhancements of TOF-DS™ software – an intuitive package offering full system control, combined with comprehensive qualitative and quantitative analysis.


Offering all the advantages of BenchTOF-HD, and incorporating Markes’ revolutionary Select-eV® variable-energy ionisation technology, BenchTOF-Select is the ultimate system for analysts requiring world-class analytical capability and productivity.

Key advantages of BenchTOF mass spectrometers include:

Better than quad-SIM sensitivity

Better than quad-SIM sensitivity but with full, reference-quality spectra (1-1500 amu) for confident identification of target compounds as well as unknowns.

Unparalleled productivity
  • High-speed acquisition allows 2 or 3 x faster sample throughput.
  • Exceptional stability minimises downtime by eliminating the need for unscheduled maintenance.
  • High sensitivity means small sample sizes and reduced sample preparation.
  • Real-time and labour-saving TOF-DS software – including dynamic background compensation (DBC) and on-the-fly deconvolution.
  • ChromCompare® automated data comparison.
Versatility and confidence for mission-critical performance
  • Compatible with all major makes of GC.
  • Sub-amu selectivity eliminates matrix interferences.
  • Regular GC, fast-GC or GC×GC – any application.
Shaping the future of GC–MS with BenchTOF-Select – A time-of-flight mass spectrometer with variable-energy electron ionisation
  • One of the world’s leading time-of-flight mass spectrometers for GC and GC×GC.
  • Exceptional performance: All the fundamental advantages of BenchTOF-HD – sensitivity, spectral quality, stability, speed and sub-amu selectivity – supported by the power of and revolutionary Select-eV variable-energy ionisation technology.
Select-eV unlocks the most challenging applications
  • Increases the absolute intensity of molecular ions.
  • Collects confirmatory low-energy spectra with structurally significant fragmentation.
  • Extends the dynamic range and limits of detection.
  • Distinguishes between compounds with identical 70 eV spectra.
Unparalleled productivity
  • Fast analysis, fast method development, minimal down-time and reduced sample preparation.
  • Real-time access to results and innovative data-mining features such as dynamic background compensation (DBC), deconvolution and ChromCompare data comparison.
  • Exceptional stability eliminates unscheduled maintenance, even when using soft ionisation.
