Title:
HYPOCHLORITE ION MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/176015
Kind Code:
A1
Abstract:
Provided is a method for measurement of a measurement sample containing hypochlorite ion by liquid chromatography-mass spectrometry, said method comprising determining the abundance of hypochlorite ion by selecting a mass chromatogram that indicates the presence of a hypochlorite ion-derived complex from a plurality of mass chromatograms obtained by liquid chromatography-mass spectrometry.
