Anatune is a proud Authorised Distributor for LECO instrumentation in the UK. Analytical instrumentation from LECO, such as the LECO Pegasus BT 4D GC GC TOFMS, are industry-leading and highly innovative, and they ensure our customers are able to overcome their complex research challenges. Namely, comprehensive two-dimensional gas chromatography.

Comprehensive two-dimensional gas chromatography (GCxGC) is a technique that has been around for over 25 years and has demonstrated high-levels of accuracy, precision, and robustness. Research has shown the benefits of GCxGC in a wide variety of applications – such as Environmental, Metabolomics, Petroleum, Food Analysis, and Aroma Profiling – as the benefits include increased peak capacity (i.e. resolution), structured two-dimensional chromatograms (i.e. contour plots), and sensitivity enhancement.

Sample characterisation is improved with a GCxGC analysis which increases confidence in analytical results achieved. The extra resolution offered by the GCxGC analysis also allows for the use of more economical detectors.

Today’s laboratories are being asked for more everyday—more samples run, more data acquired, more chemical information processed, and more results achieved—all in less time, for less money.

Therefore, the smartest investment for any laboratory looking to perform quantitative or qualitative analysis of knowns and unknowns, is the LECO Pegasus® BT 4D GCxGC-TOFMS.

The Pegasus® BT 4D offers enhanced sensitivity by coupling the bench-top Pegasus BT with a high performance GCxGC modulation system. This combination gives the Pegasus BT 4D the ability to interrogate challenging samples where the best sensitivity is needed. Unique and powerful software and hardware features simplify quantitation, while also making GCxGC easy-to-use and understand.

The Thermal Modulation System provides the highest sensitivity available on the market for those analyzing the most complex samples.

The new FLUX™ flow modulation system is an excellent option for those looking for added capability over one dimensional GC.

If you already own a compatible GC, we also have an upgrade path to add the Pegasus BT 4D capability to your existing system.

The Pegasus® BT 4D GCxGC-TOFMS give users more uptime, improved chemical data, and an increase in overall productivity and efficiency.

If you already own a compatible GC, we also have an upgrade path to add the Pegasus® BT 4D GCxGC-TOFMS capability to your existing system.

Key Features:

  • ChromaTOF®, LECO’s exclusive software designed for advance chromatography, works seamlessly with the new Pegasus BT 4D to automatically process user data and remove the guesswork involved with analyte identification and quantification. Features such as NonTarget Deconvolution®, Target Analyte Find, library searches, and an easy-to-configure interface, all come together to give users a better GCxGC experience.
  • The Pegasus BT 4D makes is easy to perform a Non-Targeted analysis for complex samples.
  • Clearly identify analytes in your sample with the unmatched sensitivity of the GCxGC modulation process.
  • Our open-style StayClean® EI source virtually eliminates downtime associated with source cleaning, which means more time running samples and less time cleaning your source.
