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. ChromaTOF® software, purpose-built for HRT+ instrumentation and GC×GC workflows, integrates advanced qualitative and quantitative tools into a single, user-friendly data system.
Key Features
- Compact benchtop design that saves valuable laboratory space
- Industry-leading sensitivity with proprietary deconvolution algorithms for clean, high-quality spectra
- High acquisition speed up to 200 spectra/s to properly define ultra-narrow GC×GC peaks (<200 ms)
- Complete historical mass-spectral record retained for future data mining and reprocessing
- Proven Pegasus reliability and durability in a modern, space-efficient format
GC×GC Performance Explained
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.
Available Configurations
