GC Time-of-Flight Mass Spectrometer
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. The Pegasus BT allows you to achieve all of the data you need from a single sample run, while powerful yet user-friendly ChromaTOF® software processes your data and removes the guesswork involved with analyte identification, quantitation, and reporting. The Pegasus BT give users more uptime, improved chemical data, and an increase in overall productivity and efficiency.
Why Choose a Time-of-Flight Mass Spectrometer?
Mass spectrometers are perhaps the greatest tool available for the analytical chemist. With the ability to ionize, sort, and measure complex chemical mixtures by their mass-to-charge ratio (m/z) with femtogram (fg) to nanogram (ng) sensitivity, it is no wonder that mass spectrometers are widely used across many industries. The mass spectrometer can be divided into three main components: ionization source, mass analyzer, and detector. While the functions of the ionization source and detector are extremely important to the function of the mass spectrometer, it is the selection of the mass analyzer that can be tailored to meet data quality objectives. Sample matrix, required detection levels, target or non-target analysis, and budget all play an important role when selecting a mass analyzer. There are typically four types of mass analyzers to choose from: time-of-flight, quadrupole, ion trap and magnetic sector.
A time-of-flight mass spectrometer (TOFMS) is ideal for discovering new compounds in your sample, quantifying targeted compounds in complex samples, and increasing throughput with fast chromatography.

Helmholtz Zentrum München (HMGU) Department “Comprehensive Molecular Analytics“, GERMANY
„This combination of ultrahigh chromatographic separation with high mass resolution might be still unique for a commercial
available end user system.“
Food Chemistry Institute Cologne, Italy
“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!”
Università degli Studi del Piemonte Orientale, Italy
„With the Pegasus BT 4D performing untargeted analysis today is very easy, thanks to the high sensitivity of the instrument, we are able to mine and analyze any type of sample! A combination of very good sensitivity, quality to price ratio and high flexibility make the Pegasus BT 4D system perfect for analysis of every sample”
Czech Academy of Science, Tschechische Republik
“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.“
TURKU Metabolomics Facility, Finland
“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 conﬁ dent that the ion source will remain clean even with dirty samples such as plasma.“
SGS Institut Fresenius GmbH Berlin, Germany
“We at SGS MOSH/MOAH group are using the GC × GC-TOFMS from LECO to separate the highly complex fractions of MOSH/MOAH contaminates in food. When you want to identify special patterns of contamination species amongst other analytics (e. g carotenoids) you need a high separation power in combination with a fast screening MS. This is provided by the LECO TOF. Actually we have a new project together with LECO and another company to quantify MOSH/MOAH fractions. The complexity of the instrumentation is high, but with the support of the application team from LECO we reach our goals.”
