Purnendu “Sandy” Dasgupta Awarded $1 Million NASA Grant
Purnendu “Sandy” Dasgupta, Hamish Small Chair in Ion Analysis of Chemistry and Biochemistry in the UT Arlington College of Science, has been awarded almost $1 million from NASA. The grant will support research into extension of the open-tubular capillary chromatography platform that Dasgupta developed for the detection and separation of ions.

The grant will support research into extension of the open-tubular capillary chromatography platform that Dasgupta developed for the detection and separation of ions.
Dasgupta is now working towards tackling the challenge of designing a portable system for liquid-based separation and detection of chiral amino acids in space. He said: “Life is centred on one type of chirality. Our objective, if we can detect amino acids, is to separate the amino acids into chiral forms. That means we’ll be able to tell whether we have an excess of one chiral form over another, or dominantly just one chiral form. In that case, it would definitely be related to life.”
Best of the Week: Food Analysis, Chemical Migration in Plastic Bottles, STEM Researcher of the Year
December 20th 2024Top articles published this week include the launch of our “From Lab to Table” content series, a Q&A interview about using liquid chromatography–high-resolution mass spectrometry (LC–HRMS) to assess chemical hazards in plastic bottles, and a piece recognizing Brett Paull for being named Tasmanian STEM Researcher of the Year.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
Determination of Pharmaceuticals by Capillary HPLC-MS/MS (Dec 2024)
December 19th 2024This application note demonstrates the use of a compact portable capillary liquid chromatograph, the Axcend Focus LC, coupled to an Agilent Ultivo triple quadrupole mass spectrometer for quantitative analysis of pharmaceutical drugs in model aqueous samples.
