Chemical Ionization Source
Available for the Pegasus GC-HRT+
Confirm your unknowns with accurate mass chemical ionization (HR-CI), a new option for the Pegasus GC-HRT+. The Pegasus GC-HRT+ is available with both electron ionization (EI) and CI sources, offering you the options of comparison with classic library spectra (EI) and superior preservation of the molecular ion (HR-CI). Save time and effort in your laboratory by more easily identifying unknowns and having more confidence in your library hits.
- Benefits of positive ion chemical ionization include:
- Confirmation of molecular ions
- More confidence in EI library matches
- Propose chemical formulae for unknown or novel compounds
- Reduce possible formulae with accurate mass data

The spectral transformations illustrated here compare EI and HR-CI. The top image is an example from a mouse liver extract, where soft ionization allows for confident confirmation of a marker involved in glycemic variability for individuals with type 2 diabetes. The bottom example demonstrates how HR-CI is ideal for forensic drug analysis, as drugs are constantly evolving and often not present in commercially available libraries. Save time and effort in your laboratory by more easily identifying unknowns and having more confidence in your library hits. |
