标准范围

本文件规定了土壤和土壤材料中炸药和相关硝基化合物（如表1所示）的测量方法。本文件旨在通过液相色谱-串联质谱（LC-MS/MS）对炸药和相关化合物进行痕量分析。通常，LC-MS/MS测量显示表1中每种化合物的LOQ（定量限）低于使用带UV检测的高效液相色谱法（HPLC）（见附录B和附录C）。在本文件规定的条件下，根据物质的不同，可以测定低至0005？mg/kg至0014？mg/kg干物质的浓度。类似的化合物，尤其是各种硝基芳烃、爆炸性化合物的副产物和降解产物，可使用该方法进行分析，前提是对其适用性进行逐案检查。

This document specifies the measurement of explosives and related nitrocompounds (as given in Table 1) in soil and soil materials. This document is intended for the trace analysis of explosives and related compounds by liquid chromatography–tandem mass spectrometry (LC-MS/MS). Generally, LC-MS/MS measurement shows the lower LOQ (limit of quantification) for each compound in Table 1 than using high-performance liquid chromatography (HPLC) with UV-detection (see Annex B and Annex C).Under the conditions specified in this document, concentrations as low as 0,005 mg/kg to 0,014 mg/kg-dry matter can be determined, depending on the substance. Similar compounds, in particular various nitroaromatics, by-products and degradation products of explosive compounds can be analysed using this method provided that the applicability is checked on a case-by-case basis.
