Your Pegasus® BT is a powerful instrument, but if you're unsure how to use some of its features, you aren't able to get the full benefit from your investment. LECO is rolling out LECOLearn, an online, on-demand training site to help you maximise your laboratory.

LECO Solutions for Metabolomics


Metabolomics presents challenges for both the analytical methods used and the data reduction required to interpret the results. No single analytical technique can be used for complete characterisation of the metabolome, and no metabolome has been completely characterised. However, GC-MS provides an established method to analyse the primary metabolome, whereas LC investigates the secondary and tertiary metabolites.

"Evaluating Oxidized Base Oils by Flow Modulated GC×GC-TOFMS" by Paul Harvath

At LECO’S GC×GC Workshop & Symposium (filmed at the LECO European Application and Training Centre, Berlin, Germany) Paul Harvath gave a talk entitled "Evaluation of Oxidized Base Oils by Flow Modulated Two-Dimensional Gas Chromatography – Time of Flight Mass Spectrometry". In his talk he gave an insight about the history and future of engine oils for cars, and how the lubricants changed over the times.

Medical Diagnosis using Breath Analysis and GC×GC-TOFMS: Optimizing Data for Accurate Treatment

At our ASMS breakfast seminars, Jean-François (Jef) Focant, Head of the Department of Chemistry and Director of the Organic and Biological Analytical Chemistry group at the University of Liège, Belgium, spoke about using our Pegasus® BT 4D and Pegasus® GC-HRT 4D for GC×GC-TOFMS on the breath of asthma patients to improve asthma treatment*. Before diving into the blood and sputum, Jef first educated us on the importance of optimizing your data.

Mass spectrometry and the history of GC-TOFMS by Alan Griffiths

 Non-targeted analysis, data science and innovation have synchronised to underpin the next generation of separation science analysis in mass spectrometry. LECO UK’s separations science product specialist Alan Griffiths explains.

“Ideas often spark one another, and chain reactions occur. As with chemical reactions, ideas can remain contained in relatively small areas before gradually spreading outward. California’s Silicon Valley is a focal point for technology. For mass spectrometry (MS), the UK’s city of Manchester is a focal point. Manchester is where the first commercial mass spectrometer built outside of the US was produced…“
