Sample preparation for instrumental analysis is of crucial importance to the quality of the test results as well as for the speed of the analysis. In liquid chromatography, SPE (solid phase extraction) is a widely used technique for concentrating analytes and for removal of matrix components.
Paraben Exposure and Childhood Obesity Risk in Preschoolers: UPLC-MS/MS Insights from Recent Study
July 14th 2025Researchers speculating that exposure to paraben in early childhood is associated with changes in satiety hormones performed analysis of urinary methyl, ethyl, propyl, and butylparaben (MeP, EtP, PrP, BuP) levels in 4–6-year-old children, using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
GC-MS Sheds Light on Chemical Communication Between Desert Locusts
July 9th 2025A multinational research team used behavioral assays and gas chromatography-mass spectrometry (GC-MS) to examine short- and long-term interactions between juvenile and adult desert locusts to test their hypothesis that cross-stage interactions influence juvenile cohesion and physiological traits.
