Select-eV®, available with BenchTOF mass spectrometers, enables the energy of ionising electrons to be changed, breaking new ground in the field of GC-MS.
Obtain reference-quality electron ionisation mass spectra with conventional full-fragmentation patterns, and repeatable 'soft-ionization' spectra with reduced fragmentation and an enhanced molecular ion
Overcome sensitivity compromises of previous approaches to soft electron ionisation, and the inconvenience of reagent gases or source exchange required with other approaches to soft ionization
Desired ionization energy simply selected as part of the method setup in the controlling software
Energies can be varied from standard 70 eV down to 10 eV
Now with Tandem Ionisation® capability, allowing fast switching between hard and soft ionization across and peak, for simultaneous acquisition of two data sets in a single run
