This application note updates the method with a high resolution IonPac AS16 4µm-2mm column. In comparison to the IonPac AS16 column, the IonPac AS16-4µm column exhibits higher peak efficiency while maintaining the same selectivity. This application note shows that using AS16-4µm column saves 3 min per injections, thereby improving productivity in perchlorate determinations in drinking water. Key performance parameters were evaluated including separation, linearity, limits of detection, accuracy, and precision. Perchlorate concentrations were determined in three drinking water samples.

Before running any samples, Thermo Scientific recommends that you first confirm the performance of the column by reproducing the lot validation report chromatogram shipped with column. Compare your results with the one reported in the quality assurance report (QAR). This record provides an eWorkflow for executing the QAR method on ICS-5000+ system. Other ICS systems can be used for this application.

Perchlorate in commercially available honey was determined on a Thermo Scientific Dionex ICS-6000 ion chromatography system with ISQ-EC single quadrupole mass spectrometer.

A new workflow based on a modified QuPPe method and IC-MS/MS supports simultaneous multi-residue analysis of grape samples for polar pesticides. The IC-MS/MS method was developed using a Thermo Scientific™ Dionex™ IonPac™ AS19 4-µm column set and a compact IC system coupled to a Thermo Scientific™ TSQ Quantis™ triple quadrupole mass spectrometer. The results showed that the sensitivity, linearity,retention time precision, and recovery align with the SANTE/11813/2017 method performance criteria. The method provides lower LOQs than EU MRLs.
