A Little Blood Goes A Long Way
A new technique, using liquid chromatography-mass spectrometry (LC-MS), has now made it easier for scientists and researchers to obtain any information they need from very small amounts of blood.
A new technique, using liquid chromatography-mass spectrometry (LC-MS), has now made it easier for scientists and researchers to obtain any information they need from very small amounts of blood.
The technique, which was developed by a group of researchers from the University of Colorado led by anesthesiologist Jeffry Galinkin, uses a new method of screening miniscule amounts of dried blood for chemicals.
This new method will reportedly solve the current problem that researchers have faced with obtaining a sufficient amount of blood from infants to test for chemicals. According to Galinkin, drug dosing guides for infants is the primary priority for the researchers, however it is only one of many possible applications of the technique, which include diagnosing HIV or tuberculosis, and even testing for banned substances in athletes.
New Study Reviews Chromatography Methods for Flavonoid Analysis
April 21st 2025Flavonoids are widely used metabolites that carry out various functions in different industries, such as food and cosmetics. Detecting, separating, and quantifying them in fruit species can be a complicated process.
Quantifying Terpenes in Hydrodistilled Cannabis sativa Essential Oil with GC-MS
April 21st 2025A recent study conducted at the University of Georgia, (Athens, Georgia) presented a validated method for quantifying 18 terpenes in Cannabis sativa essential oil, extracted via hydrodistillation. The method, utilizing gas chromatography–mass spectrometry (GC–MS) with selected ion monitoring (SIM), includes using internal standards (n-tridecane and octadecane) for accurate analysis, with key validation parameters—such as specificity, accuracy, precision, and detection limits—thoroughly assessed. LCGC International spoke to Noelle Joy of the University of Georgia, corresponding author of this paper discussing the method, about its creation and benefits it offers the analytical community.
