BenchTOF-Select™

BenchTOF-Select unites the power of BenchTOF-HD with Select-eV – Markes’ revolutionary variable-energy ionisation technology.

Product benefits

  • Expand your analytical capability with Select-eV® – confidently identify unknowns and routinely distinguish between structurally similar compounds.
  •  Acquire hard and soft ionisation data simultaneously using Tandem Ionisation® – for unparalleled productivity.
  •  Enjoy greater confidence in identification, thanks to BenchTOF-Select’s reference-quality 70 eV spectra and complementary soft EI spectra.
  •  Eliminate the hassle and expense associated with other soft ionisation techniques.
  •  Expand your laboratory’s capability by improving detection of trace-level compounds in complex matrices.
  •  Speed up analysis of complex samples with fast GC and GC×GC.
  •  Streamline your instrument control, method development and data analysis with TOF-DS™ software and its optional ChromSpace® GC×GC module.

Features

  •  Unique Select-eV® and Tandem Ionisation® capability, giving complementary soft EI spectra with enhanced molecular ions and reduced fragmentation in a single run.
  •  SIM-like sensitivity for trace-level analysis of targets and unknowns in a single run.​
  •  Reduced chemical noise/background, improving detection limits for target compounds.
  •  Powerful TOF-DS™ software for instrument control and data analysis, including real-time processing​ and unlockable parameters for fast method development.
  •  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.​
  • Robust ion source design – meaning source cleaning is recommended only once a year, as part of the routine annual service.
