Pegasus BT 4D GCxGC-TOFMS

Pegasus BT 4D GCxGC-TOFMS

 Time-of-Flight Mass Spectrometer

The Pegasus® BT 4D delivers enhanced sensitivity by integrating our compact Pegasus BT system with a high-performance GC×GC modulation platform. This powerful combination enables precise analysis of complex and challenging samples where maximum sensitivity is essential. Engineered with robust software and hardware features, the Pegasus BT 4D simplifies quantitation and makes GC×GC more accessible and user-friendly than ever before.

For those working with highly intricate sample matrices, our traditional thermal modulation system offers the highest sensitivity available on the market.

Alternatively, the FLUX™ flow modulation system provides an excellent option for users seeking enhanced capabilities beyond conventional one-dimensional GC, with added flexibility and performance.

Features

  • Pegasus® BT 4D: Features & Advantages

    Streamlined Data Analysis with ChromaTOF®
    LECO’s exclusive ChromaTOF® software is designed for advanced chromatography and works seamlessly with the Pegasus BT 4D. It automates data processing and removes the guesswork from analyte identification and quantification. Key features include:

    • NonTarget Deconvolution®

    • Target Analyte Find

    • Integrated Library Searches

    • User-friendly, configurable interface

    Together, these tools deliver a powerful and intuitive GC×GC experience.

    Comprehensive Non-Targeted Analysis
    Curious about what’s in your sample? The Pegasus BT 4D makes non-targeted analysis simple and effective, helping uncover unknown compounds in even the most complex sample matrices.

    Exceptional Sensitivity
    Leverage the unmatched sensitivity of the GC×GC modulation process to confidently detect and identify trace-level analytes, even in difficult-to-analyze samples.

    Minimized Maintenance with StayClean® EI Source
    The innovative open-style StayClean® EI Source drastically reduces downtime from source cleaning, allowing you to spend more time running samples—and less time performing maintenance.

    What is GC×GC?

    Comprehensive Two-Dimensional Gas Chromatography (GC×GC) has been a cornerstone of high-resolution separation science for over 25 years. While once considered a research-only technique, GC×GC has evolved into a practical, validated tool for routine analysis in fields such as:

    • Environmental monitoring

    • Metabolomics

    • Petroleum and petrochemical testing

    • Food safety

    • Fragrance and flavor profiling

    Proven Benefits:

    • Increased Peak Capacity: Greater resolution helps detect more compounds within a single analysis.

    • Structured 2D Chromatograms: Visualize complex data using intuitive contour plots.

    • Sensitivity Enhancement: Capture low-abundance analytes with improved clarity.

    Why GC×GC in Routine Labs?
    GC×GC enables laboratories to:

    • Combine multiple analyte classes in a single run, reducing sample prep and instrument time

    • Reduce manual data review thanks to sharper peaks and better spectral matches

    • Enhance data confidence, leading to better-informed decisions

    • Use more cost-effective detectors like FID or ECD without sacrificing analytical performance
