LECO Pegasus GC-HRT+

Ultra-high-resolution GC-TOFMS with up to 50,000 FWHM, <1 ppm mass accuracy, and 200 spectra/s. Pegasus GC-HRT+ delivers unmatched sensitivity and confident identification in complex samples.

Now with even higher sensitivity, the Pegasus GC-HRT+ is designed to meet the most demanding analytical challenges. This high-performance GC-TOFMS delivers industry-leading mass accuracy, full-range acquisition at exceptional speed, precise isotopic abundance, and ultra-high mass resolution—all within a single injection.Folded Flight Path (FFP) technology combined with a novel data acquisition system enables up to 50,000 FWHM resolution, &lt;1 ppm mass accuracy, and acquisition rates up to 200 spectra/s, supporting rich analyte discovery and high-confidence identification in highly complex samples.<h3>Key features</h3><ul><li>Mass accuracy ≤1 ppm with peak capacity at least 2× higher than conventional MS platforms</li><li>Encoded Frequent Pushing (EFP) for markedly increased sensitivity, expanded dynamic range, and wide mass range</li><li>Folded Flight Path (FFP) technology for ultra-high resolution, enhanced sensitivity, and advanced TOF focusing</li><li>KADAS® ion-statistics-based acquisition to reduce noise, ensure mass accuracy, and minimize file size</li><li>Ultra High Resolution + HRD to resolve highly isobaric ions (mass differences ~0.02 amu)</li><li>Multi-Mode Source (MMS): EI, Positive CI, and ECNI in one system</li></ul><h3>Models</h3><ul><li>Pegasus GC-HRT+ – Full-scale GC-TOFMS</li></ul><h3>Options</h3><ul><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/82">L-PAL3 Automated Sample Injector</a></li></ul>

LECO Pegasus GC-HRT+ 4D

High-resolution GC×GC-TOFMS system combining extreme separation power, up to 200 spectra/s acquisition, and advanced HR deconvolution for confident identification of unknowns in complex samples.

The Pegasus GC-HRT+ 4D from LECO combines comprehensive two-dimensional gas chromatography (GC×GC) with high-resolution time-of-flight mass spectrometry (TOFMS) and advanced High-Resolution Deconvolution (HRD). Designed for the most complex sample matrices, the system enables detection, separation, and confident identification of more analytes than ever before. <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/41">ChromaTOF® software</a>, purpose-built for HRT+ instrumentation and GC×GC workflows, integrates advanced qualitative and quantitative tools into a single, user-friendly data system.<h3>Key Features</h3><ul><li>Compact benchtop design that saves valuable laboratory space</li><li>Industry-leading sensitivity with proprietary deconvolution algorithms for clean, high-quality spectra</li><li>High acquisition speed up to 200 spectra/s to properly define ultra-narrow GC×GC peaks (&lt;200 ms)</li><li>Complete historical mass-spectral record retained for future data mining and reprocessing</li><li>Proven Pegasus reliability and durability in a modern, space-efficient format</li></ul><h3>GC×GC Performance Explained</h3>GC×GC achieves exceptionally high peak capacity by trapping compounds eluting from the first column and reinjecting them into a second column for rapid secondary separation. These second-dimension separations occur within seconds, producing extremely narrow peaks that demand very high spectral acquisition rates. The Pegasus GC-HRT+ 4D meets and exceeds this requirement, enabling robust spectral deconvolution and confident compound identification in highly complex samples.<h3>Available Configurations</h3><ul><li>Pegasus GC-HRT+ 4D with Liquid Nitrogen Thermal Modulator</li><li>Pegasus GC-HRT+ 4D with Cryogen-Free Modulator</li></ul><h3>Optional Accessories</h3><ul><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/82">L-PAL3 Autosampler</a></li></ul>
