ISO 11916-2:2013规定了土壤和土壤材料中爆炸物和相关化合物(硝基芳烃和硝胺)的测量。ISO 11916-2:2013旨在使用电子捕获检测器(ECD)或质谱仪(MS)作为检测器,通过气相色谱(GC)对炸药和相关化合物进行痕量分析。
当需要在低检测水平下对化合物进行可靠和具体的识别时,例如用于评估被2,6-DNT污染的土壤的毒性潜力时,可以使用ISO 11916-2:2013。
在ISO 11916-2:2013规定的条件下,根据物质的不同,可以测定低至0.05 mg/kg干物质的浓度。类似的化合物可以用这种方法进行分析。然而,这有待实验验证。本方法不适用于己根(RDX)、八元(HMX)、己基、四元和五硝基(PETN)的分析。
ISO 11916-2:2013 specifies the measurement of explosive and related compounds (nitroaromatics and nitroamines) in soils and soil materials. ISO 11916-2:2013 is intended for the trace analysis of explosives and related compounds by gas chromatography (GC) using electron capture detector(s) (ECD) or a mass spectrometer (MS) as detector.
ISO 11916-2:2013 can be used when reliable and specific identification of the compounds at low detection levels is required, e.g. for the evaluation of the toxic potential of soils contaminated with 2,6-DNT.
Under the conditions specified in ISO 11916-2:2013, concentrations as low as 0,05 mg/kg dry matter can be determined, depending on the substance. Similar compounds may be analysed using this method. This is, however, to be verified experimentally. This method is not suitable for the analysis of hexogen (RDX), octogen (HMX), hexyl, tetryl and nitropenta (PETN).
