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.
Analysis of PFAS in Milk by LC-MS/MS
May 15th 2025Dairy milk is one commodity that can be impacted by environmental contaminants, such as PFAS, so it is important to implement extensive, robust, and accurate testing. In this work, a sensitive and reliable method was developed for the analysis of PFAS in milk by LC-MS/MS at levels as low as 0.01 µg/kg.
