The authors demonstrate a new detection method, indirect suppressed conductivity, for various anions of weak acids separated by ion chromatography. They analyzed three groups of anions, including amino acids such as leucine, taurine, phenylpropionic acid, and phenol; malic and tartaric acids; and lactic, formic, and benzoic acids. The authors describe the mobile phases, detection limits, and correlation coefficient of rectilinear relationships for each anion type.

October 17th 2024This review aims to provide a summary of the most current analytical techniques and their applications in per- and polyfluoroalkyl substances (PFAS) research, contributing to the ongoing efforts to monitor and mitigate PFAS contamination.
Systematic Evaluation of HILIC Stationary Phases for MS Characterization of Oligonucleotides
Hydrophilic interaction chromatography–mass spectrometry (HILIC-MS) offers a flexible and efficient alternative to ion-pairing reversed-phase liquid chromatography (IP-RPLC) for oligonucleotide analysis, with column selectivity and mobile phase pH being key factors in optimizing retention and detection.
