LECO Pegasus GC-HRT 4D time-of-flight mass spectrometer

LECO has announced the Pegasus GC-HRT 4D, claimed to combine the industry standard for comprehensive GCxGC with high-performance time-of-flight mass spectrometry. The GCMS innovation provides scientists with the ability to investigate complex samples and identify unknown analytes with confidence.

The company’s ChromaTOF-HRT brand software with High Resolution Deconvolution (HRD) is tailored to get the most out of high-resolution data using NIST and accurate mass libraries. Workflows are enabled by features such as pseudomolecular ions via chemical ionisation, leveraging retention-time matching, isotope patterns and mass accuracy of deconvoluted fragments. All these features lead to confident identification of unknown species.

With mass accuracies of 1 ppm and increased peak capacity potential, the product is suitable for solving the problem of coelution and comprehensively characterising complex samples.
