标准编号：ISO 5120:2023

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

本文件规定了一种使用液相色谱法与串联质谱法（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进行分析以及干燥土壤中高氯酸盐含量的计算。在本文件规定的条件下，定量限（LOQ）约为4,6？μ g/kg-干燥土壤。

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.
