T/ZJATA 0023-2024 Determination of High Chlorate in Water by Ion Chromatography-Mass Spectrometry/Mass Spectrometry (IC-MS/MS)

Scope

Scope: This document describes the ion chromatography-mass spectrometry/mass spectrometry method for the detection of perchlorate in water. This document is applicable to the determination of perchlorate content in surface water, groundwater, precipitation, and drinking water (including mineral water, tap water, and purified water). When the sample volume is 10 μL, the method's detection limit for perchlorate is 0.05 μg/L, and the determination limit is 0.20 μg/L. Main technical content: The standard includes the method principle, instrumentation and equipment, reagents or materials, samples, detection steps, quality control, etc. It establishes a method in which perchlorate in water is separated by an anion exchange column and detected by a mass spectrometer, and quantified using an isotope internal standard method. This method has the advantages of wide applicability, fast detection speed, and accurate and reliable test results, and is suitable for the determination of perchlorate content in surface water, groundwater, and drinking water (including mineral water, tap water, and purified water). It also has certain innovation, and the relevant technical indicators are at an advanced level in China.
