Ion chromatography in water analysis - Wiley Analytical Science
Web4 sep. 2024 · Nowadays the ion chromatographic determination of anions is a well-established method in analytical chemistry. IC can be used for separation, sample preparation and quantification. IC is a reliable and sensitive method with a good reproducibility, is fully automated and moderate in costs. WebIons are transmitted from the source through the quadrupoles (quadrupoles are in RF only mode) into the ion trap. After the ion trap is filled, the ions are scanned out axially to the detector. This provides a full scan analysis of all the analytes entering that QTRAP System at that point in time.
