Tandem Ionisation for Mass Spectrometry speeds up full sample characterisation

publication date: Jun 29, 2016
author/source: Markes International Limited

Tandem Ionisation® allows both soft and classical electron ionisation mass spectra to be acquired simultaneously across an entire GC or GC×GC run.

BenchTOF brochure This provides analysts the capability to acquire both soft EI spectra and conventional 70 eV spectra at the same time in an integrated workflow. This means that a single GC or GC×GC run can provide all the information needed to fully characterise a sample for both target compounds and unknowns. Tandem Ionisation, unique to Markes, generates two spectra from a single peak by rapid switching between ‘soft’ ionisation (typically 10–16 eV) and conventional ‘hard’ ionisation (70 eV), and is fully automated by Markes’ TOF-DS™ software for BenchTOF.
