"I have used the LECO BT4D for the separation, identification, and quantification of anabolic steroids.

The advantages of the GC×GC system to separate stereoisomers in a complex matrix means time can be saved from doing complex sample preparation and extraction procedures. The ability to separate and quantify low levels of target analytes from high levels of matrix interferences has been key to my work. With LECO’s user-friendly ChromaTOF software, expert application scientists, and fantastic technical service team, LECO is a reliable and trusted research partner."

"In 2013, I became responsible for overseeing the department’s analytical suite which included a LECO PEGASUS® 4D GC×GC TOF MS as our flagshipinstrument. I had no experience in gas chromatography and found even a standard GCMS daunting. Over the past years, I received extensive support from LECO. Especially withsupport from LECO UK the instrument is still running strong a decade after purchase. I anticipate it will go for another decade and then some."

"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."

"Our virtual metabolomics research center has six GC-MS instruments, and the LECO PEGASUS® 4D is the crown jewel of our science park. The results of GC-MS profiling performed using GC×GC technologies has madea strong impression on users and has seriously improved the quality of ourpublications. The fast-scanning capabilities of the TOF-analyzer effectively augment the dataobtained on the ordinary quadrupole, especially when working with the most complexmatrices which are most often the subject of metabolomics analysis. The reliability of the device is especially deserving of praise. The equipment can withstand a very demanding load with constant, round-the-clock operation."
