Using LC-MS/MS Analysis for PFAS Detection in Biological Samples and Serum
November 1st 2024Per- and polyfluoroalkyl substances (PFAS) are exceptionally versatile chemicals and have seemingly endless applications. Due to their persistent nature; prevalence in blood, food and environment; and emerging toxicity, there is a significant concern for their presence in the human body. Analysis is especially complicated due to background contamination in laboratory supplies and system. This paper will discuss sample preparation and LC-MS/MS analysis of an expanded panel of PFAS compounds in serum.
Robust Oligonucleotide Molecular Weight Confirmation via LC/MS
October 31st 2024Oligonucleotides—therapeutic agents for difficult-to-treat diseases—rely on precise molecular weight confirmation to ensure quality during development. Experts from Agilent Technologies explore the challenges of liquid chromatography-mass spectrometry (LC/MS) analysis in oligonucleotide synthesis, as well as strategies for accurate deconvolution, method development, and optimal equipment selection.
