Chemical Ionization Source

Save time and effort in your laboratory by easily identifying unknowns and having more confidence in your library hits. The chemical ionization (HR-CI) source for the Pegasus GC-HRT+ allows users to dramatically change their high resolution GC/MS information with never before seen mass accuracy and resolution on pseudo-molecular ions. The Pegasus GC-HRT+ is available with both electron ionization (EI) and chemical ionization (CI) sources, providing the option of comparison with classic library spectra (EI), and preservation of the molecular ion (CI). Together, the HR-CI source and the Pegasus GC-HRT+ provide a complete package for high-throughput/high-information content analysis, with resolution up to 50,000 FWHM, mass accuracies less than 1 ppm, and acquisition rates up to 200 spectra/second—all with high-integrity isotopic abundance measurements to facilitate rich information content and high-confidence analyte identification. Click here to learn more.
