LECO product profile
Routine Pegasus® 4D GCxGC-TOFMS optimisation is now even easier. Variable Modulation Times (VMT) feature was designed and implemented into LECO’s ChromaTOF® single software platform for even more flexibility. Traditional GCxGC uses a fixed modulation period and can result in an analytical compromise to the 1st dimension separation. The advantage of VMT enables the operator to specify at the click of a button their own and different modulation times throughout the GCxGC run. Typically, applications benefiting from GCxGC separations are matrix heavy &/or are complex samples containing a broad range of analytes. In such complex mixtures, early eluting and more volatile analytes actually require shorter modulation times whilst later eluting analytes (high boilers) require much longer modulation times. Using the new LECO VMT programming style results in graduated Pegasus 4D® GCxGC-TOFMS chromatograms in the 2nd dimension and so preserves the valuable separation in the first dimension. This feature maximizes resolution in both the first and second dimensions and is compatible with LECO’s traditional LN2 and Consumable Free (CF) Pegasus 4D® GCxGC-TOFMS instruments.
Join the experts in the field who routinely operate the Pegasus 4D® GCxGC-TOFMS and learn from their experiences. The 2nd European GCxGC Symposium takes place 20th & 21st September, University Regensburg, Germany. Registration is open, for more information contact the LECO Separation Science team.

Investigating the Protective Effects of Frankincense Oil on Wound Healing with GC–MS
April 2nd 2025Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).
Evaluating Natural Preservatives for Meat Products with Gas and Liquid Chromatography
April 1st 2025A study in Food Science & Nutrition evaluated the antioxidant and preservative effects of Epilobium angustifolium extract on beef burgers, finding that the extract influenced physicochemical properties, color stability, and lipid oxidation, with higher concentrations showing a prooxidant effect.
Rethinking Chromatography Workflows with AI and Machine Learning
April 1st 2025Interest in applying artificial intelligence (AI) and machine learning (ML) to chromatography is greater than ever. In this article, we discuss data-related barriers to accomplishing this goal and how rethinking chromatography data systems can overcome them.
