Minimizing the Effect of Sample Preparation on Measurement Uncertainty

Researchers 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).

In episode #37 of Analytically Speaking, podcast host Dr. Jerry Workman speaks with Dr. Austin Daniels, application scientist for Yokogawa Fluid Imaging Technologies, about flow imaging microscopy (FIM), a new technology for sub-visible particle characterization in biologics.

This week, LCGC International published a variety of articles on hot topics in separation science. Several analytical techniques were covered in these articles, including gas chromatography–mass spectrometry (GC–MS) and liquid chromatography–MS (LC–MS).

In a new study, researchers from the University of Milan used high-performance liquid chromatography (HPLC) to phytochemically profile residual leaves of Carciofo di Malegno, a traditional Italian artichoke variety.

A 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.
