On-line chloride removal from ion chromatography for trace-level analyses of phosphite and other anions by coupled ion chromatography-inductively coupled plasma mass spectrometry

CONCLUSIONS: The on-line removal mechanism works well for simplifying sample matrices. It removes the need for costly pre-analytical sample treatment with OnGuard columns. We confirm that IC/ICPMS is the most powerful technique for quantifying phosphite in natural solutions. The new chloride-removal method may also be applicable to analyses of other anions.PMID:38073202 | DOI:10.1002/rcm.9665
