I use LECO PEGASUS® BT 4D to separate, identify and quantify secondary metabolites of various organisms. The advantages of the GC×GC system in separation of multi-component mixtures allow us to separate and identify a huge number of compounds in every samples. The ability to separate and quantify low levels of target analytes in mixtures simultaneously with the major components presented at a high level of concentration and to separate coeluted compounds is a great advantage of two-dimensional GC in comparison with one-dimensional GC. The user-friendly ChromaTOF software and excellent technical support make LECO a reliable partner for researcher. Since we started working on this equipment, our results have become more accurate and comprehensive, and our research has reached a new level.
In our lab, the GC×GC-MS device installed by LECO has been a game-changer for metabolic profiling, especially in our multiomics study exploring the intricacies of obesity in young adults. Its sensitivity has been crucial in identifying and quantifying metabolites, even at low concentrations, essential for uncovering subtle changes in the metabolome. Our experience with PEGASUS® BT 4D device has been exceptionally positive, significantly due to the exceptional support of the service team, ensuring the smooth operation and optimal performance of our instrument.

"Pegasus BT is the perfect choice for identifying well-known metabolites at low concentration level in our sample, and also discovering new compounds. The most surprising advantage of the BT system is the ion source robustness! We usually work with dirty and complex samples, but we have never observed drop of sensitivity during our analyses.This reduces the time and cost of our analyses!"

"We use the LECO Pegasus BT instrument for the quantification of small polar metabolites. We developed a hybrid method where we quantitate 51 metabolites with standard curves and screen for any other small polar metabolites in a wide range of biological samples. This assay has a great dynamic range thanks to the sensitivity of the BT. The StayClean® ion source allows us to run hundreds of samples in a batch and be confident that the ion source will remain clean even with dirty samples such as plasma."

"Compared to GC equipped with a single column, the Pegasus 4D enabled me to separate unbelievable number of analytes! Tens of thousands of separated peaks in one run was not an exception. But where the separation was not perfect, ChromaTOF software and its deconvolution algorithm did the job. Such excellent ‘separating power’ helped me discover new types of plant PCB metabolites."
