According to Schenk, the widespread popularity of the hydraulic fracturing technique coupled with horizontal drilling has introduced a new set of needs for analytical testing. Proppants and friction reducers are used in the process of hydraulic fracturing to improve productivity, but their behavior in downhole conditions have not been fully characterized. Leaching from resin-coatings of the proppants and byproducts formed under high-temperature and pressure can be of concern to productivity and groundwater contamination. In these experiments, gas chromatography–mass spectrometry (GC–MS), GC–vacuum ultraviolet spectroscopy (VUV), and liquid chromatography (LC) were all examined to identify and quantify compounds from various resin-coated proppants and friction reducers used in the fracking procedure.

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.
