Determination of aromatic sulfonic acids in aqueous environmental samples by anion-exchange chromatography coupled to particle beam mass spectrometry and UV spectrophotometry
TL;DR: Aromatic sulfonic acids are determined in water using anion-exchange liquid chromatography as discussed by the authors, and the average recoveries are 82% for six monosulfonic acids (spiked at 0.1, 1.0 and 100 ppm) and 95% for two disulfonic acid (spiking at 1.5, 2.0, and 3.5 ppm) (S.D.

Anion-exchange chromatography particle beam mass spectrometry for the characterization of aromatic sulfonic acids as the major organic pollutants in leachates from Stringfellow, California
TL;DR: In this paper, anion exchange liquid chromatography with detection via particle beam mass spectrometry (electron impact and negative chemical ionization) and UV absorption spectrophotometry is used to characterize target and nontarget compounds in lyophilizates from three Stringfellow hazardous waste leachates - upstream, downstream, and a charcoal-treated mixture.

Analysis of target and nontarget pollutants in aqueous leachates from the hazardous waste site Stringfellow, California, via ion chromatography - particle beam and inductively coupled plasma mass spectrometry
TL;DR: In this paper, an ion exchange chromatography particle beam mass spectrometer (PB/MS) based method for the detection of the target compound 4-chlorobenzene sulfonic acid (a contamlnant found in hazardous waste leachates) and also for nontarget pollutants in aqueous leachate samples from the Stringfellow hazardous waste site in California.
