标准摘要
[中文适用范围]： 本文件规定了一种使用液相色谱串联质谱法 (LC-MS/MS) 测定土壤和类土壤材料中高氯酸盐的方法。它定义了样品的预处理（包括干燥和筛分）、提取、清理、使用 LC-MS/MS 进行分析以及计算干土中高氯酸盐含量。在本文件规定的条件下，定量限 (LOQ) 约为 4.6 μg/kg-干土。 [外文原描述]： 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.
