Tandem Ionisation - Time-of-Flight Mass Spectrometry

Award-winning Tandem Ionisation enables easy switching between hard and soft ionisation to generate complementary information about each component, increasing the dimensionality of your analysis. Soft and hard ionisation spectra are obtained simultaneously across a single run, for both GC and GC×GC analyses, allowing comprehensive characterisation of complex samples with none of the historical hassle associated with soft ionisation. Supplied as standard with the BenchTOF-Select mass spectrometer, soft EI allows you to identify isomers not differentiated by other GC–MS systems, by providing complementary spectra for compounds that are indistinguishable at 70 eV.
