BenchTOF Time-of-Flight Mass Spectrometers from Markes for GC-MS and GCxGC

The Markes BenchTOF series of time-of-flight mass spectrometers offer high quality of results and excellent productivity for your GC-MS experiments. The models in this series include:

BenchTOF-Evolve™

BenchTOF-HD™

BenchTOF-Select™

BenchTOF-Evolve

The BenchTOF-Evolve provides high sensitivity equivalent to secondary-ion systems, and full spectral information, all while integrating seamlessly with your existing GC-MS workflow.

BenchTOF-Evolve is perfect for any analyst wishing to realise the benefits of TOF MS without the need for extensive training or disruption to existing workflows.

Key Features

BenchTOF-Evolve instrument control software compatible with a number of leading GCs and autosamplers.

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

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

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

Long-term stability of analyte response for reduced downtime.

BenchTOF-HD

The BenchTOF-HD offers excellent sensitivity and improved productivity for a wide range of GC applications.

The spectrometer offers better sensitivity than quad-SIM with full reference-quality spectra (m/z 1–1500 amu). It is supplied with the TOF-DS software, including on-the-fly deconvolution and dynamic baseline compensation (DBC), for full system control.

Key Features

The main features of the BenchTOF-HD spectrometer are as follows:

Better sensitivity than quad-SIM

Rapid-speed acquisition enables 2 or 3x faster sample throughput

High sensitivity reduces sample preparation and eliminates the need for large-sized samples

TOF-DS software

ChromCompare^® automated data comparison

Excellent stability eliminates unscheduled maintenance and reduces down-time

Sub-unit mass selectivity reduces matrix interferences

Suitable for regular GC, fast GC and GC×GC applications

Compatible with all major makes of GC

Upgrades to Select-eV^® variable-energy ionisation

BenchTOF-Select Spectrometer

The BenchTOF-Select spectrometer features variable-energy electron ionization. This spectrometer combines the power of BenchTOF-HD, such as sensitivity, speed, stability, spectral quality and sub-unit mass selectivity, with the Select-eV variable-energy ionisation technology and the TOF-DS software to deliver excellent performance.

The BenchTOF-Select spectrometer is suitable for researchers requiring exceptional analytical capability and productivity. The Select-eV variable-energy ionisation technology improves the absolute intensity of molecular ions, expands the dynamic range and limits of detection, gathers confirmatory low-energy spectra with structurally major fragmentation, and differentiates between compounds with similar 70 eV spectra.

Key Features

The main features of the BenchTOF-Select spectrometer are:

Rapid analysis, fast method development, minimum down-time and reduced sample preparation

Select-eV variable-energy ionisation technology resolves complex applications

Excellent stability prevents unscheduled maintenance, even when utilizing soft ionization

Real-time access to results

Innovative data-mining features such as deconvolution, dynamic baseline compensation (DBC) and ChromCompare data comparison
