LECO Chemical Ionization Source

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 HR-CI sources, offering you the option of comparison with classical library spectra (EI) and superior preservation of the molecular ion (HR-CI).

Benefits of Positive ion Chemical Ionization

• 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 above compare and - . The left side is an example from a mouse liver extract,EI HR CI where soft ionization allows for confident confirmation of a marker in glycemic variability for individuals with type 2 diabetes. The right side demonstrates how - is ideal for forensic drug analysis, as drugs are constantly evolving andHR CI often not present in commercially available libraries.

Standard Features
