BenchTOF2 – High-speed TOF mass spectrometer for GC and GC×GC

BenchTOF2 is a time-of-flight mass spectrometer optimised for GC and GC×GC workflows that require high sensitivity, fast acquisition and rich spectral detail. With acquisition rates up to 400 Hz and <50 ppm mass accuracy, it captures full-spectrum data across narrow chromatographic peaks – essential for confident identification in complex, non-targeted analyses. Combining powerful performance with a compact benchtop footprint, BenchTOF2 is ideal for both routine and advanced GC–MS applications.

Figure 2. Split injection used to measure triplicate test of MTBE, hexane, o-xylene, and 1-methylnaphthalene comparing different solvents (methanol, methylene chloride) and column insertion distances starting with 0.5 mm, 5.0 mm, 10.0 mm, 15 mm, and 20.0 mm. Methanol had the best performance at the 5.0 mm insertion distance and methylene chloride looked slightly better at the 0.5 mm. We would still recommend not going below the 5.0 mm manufacturer recommended insertion distance.
