Simultaneous hard and soft ionisation for mass spectrometry

Technical note: Tandem Ionisation® – Revolutionary soft ionisation to enhance confidence in identification

This technical note describes the use of Tandem Ionisation for BenchTOF2mass spectrometers, to acquire both hard (70 eV) and soft (10–20 eV) electron ionisation (EI) in a single analysis. As well as describing the theoretical background to the technique and the benefits that stem from soft EI, we point out how Tandem Ionisation breaks new ground by providing sample characterisation in a single, streamlined workflow.
