Researchers Develop New Method for Drug Testing
US researchers have developed a new LC-MS-MS method of detecting if athletes have taken drugs to artificially boost testosterone and increase physical performance.
US researchers have developed a new LC-MS-MS method that is more senstive for detecting if athletes have taken drugs to artificially boost testosterone and increase physical performance. Previous testing methods used GC-MS to compare the ratio of testosterone to epitestosterone and determine if performance enhancing drugs were taken. However, measuring the T/E concentrations is difficult due to the low levels present in urine.
According to the lead researcher, Dr Jonathan Danaceau of the University of Utah, the new method "means that we can determine the T/E ratio in a sample with greater confidence, and therefore be in a better position to spot doping violations without falsely accusing innocent athletes."
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.
