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.
LCGC 18(2), 200–204 (2000).Evaluating the Accuracy of Mass Spectrometry Spectral Databases
May 12th 2025Mass spectrometry (MS) can be effective in identifying unknown compounds, though this can be complicated if spectra is outside of known databases. Researchers aimed to test MS databases using electron–ionization (EI)–MS.
Detecting Hyper-Fast Chromatographic Peaks Using Ion Mobility Spectrometry
May 6th 2025Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.
Sorbonne Researchers Develop Miniaturized GC Detector for VOC Analysis
April 16th 2025A team of scientists from the Paris university developed and optimized MAVERIC, a miniaturized and autonomous gas chromatography (GC) system coupled to a nano-gravimetric detector (NGD) based on a NEMS (nano-electromechanical-system) resonator.
