Rapid Analysis of Environmental Contaminants by Fast GC–TOF MS with Select-eV Variable-Energy Electron Ionisation

This application note shows that BenchTOF time-of-flight mass spectrometers provide a robust, high-performance and high-throughput solution for screening multiple trace-level environmental contaminants. Revolutionary variable-energy electron ionization is also shown to aid compound identification and enhance the selectivity and sensitivity of analyses by generating secondary (qualifying) mass spectra with reduced fragmentation and a stronger molecular ion signal.
