Leco Pegasus GC-HRT with chemical ionisation source

Leco Corporation has announced a chemical ionisation (HR-CI) source for the Pegasus GC-HRT (high resolution time-of-flight mass spectrometer). The field-upgradable option empowers users to dramatically change their high-resolution GC/MS information with high mass accuracy and resolution on pseudomolecular ions. The mass spectrometer is available with both electron ionisation (EI) and HR-CI sources, providing the option of comparison with classic NIST spectra (EI) and preservation of the molecular ion (HR-CI).

Together, the 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/s - all with high-integrity isotopic abundance measurements to facilitate rich information content and high-confidence analyte identification. ChromaTOF-HRT software utilises True Signal Deconvolution for accurate peak identification, seamless data handling and compatibility with the NIST library.
