Soil quality — Determination of perchlorate in soil using liquid chromatography-tandem mass spectrometry (LC-MS/MS)

Qualité du sol — Détermination du perchlorate dans le sol par chromatographie en phase liquide couplée à la spectrométrie de masse en tandem (CL-SM/SM)

Abstract / scope

This document specifies a method for determining of perchlorate in soil and soil-like materials using liquid chromatography connected to a tandem mass spectrometry (LC-MS/MS). It defines pretreatment (including drying and sieving) of sample, extraction, clean-up, analysis using LC-MS/MS, and calculation of perchlorate content in dry soil.

Under the conditions specified in this document, the limit of quantitation (LOQ) is approximately 4,6 μg/kg-dry soil.
