中文名称：土壤质量 用液相色谱-串联质谱法（LC-MS/MS）测定土壤中的高氯酸盐
英文名称：Soil quality — Determination of perchlorate in soil using liquid chromatography-tandem mass spectrometry (LC-MS/MS)
发布日期：2023-07
标准范围
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.
