New Variable-Energy Electron lonisation Technology Launched

摘要

Markes International has announced the launch of a variable-energy electron ionisation source technology for GC-MS, Select-eV~R. By enabling the energy of ionising electrons to be changed, Select-eV breaks new ground in the field of GC-MS. It allows the production of reference-quality electron ionisation mass spectra with conventional full-fragmentation patterns, and repeatable 'soft-ionisation' spectra exhibiting reduced fragmentation and an enhanced molecular ion.
