BS PD ISO/TR 18818:2017描述了二乙醇胺快速取样和鉴定的筛选方法 用气相色谱-质谱法测定化妆品和化妆品原料中的（DEA） （GC-MS）。本方法不适用于DEA相关成分的检测和/或量化。 当使用该方法分析不熟悉的样本矩阵时，建议分析员确认 技术在其矩阵中的适用性和灵活性。在规定的条件下，该方法可在DEA水平为1000 mg/kg时进行可靠的定量 (0,1 %).但是，浓度较低（<0.1%）或其他不寻常成分的样品或 特性可能会带来阻碍直接使用的困难（例如，峰值拖尾） 这种方法的优点。交叉引用:ASTM D7599-09SN/T 2107-2008购买本文件时可获得的所有现行修改件均包含在购买本文件中。

BS PD ISO/TR 18818:2017 describes a screening method for rapid sampling and identifying of diethanolamine (DEA) in cosmetics and raw materials used in cosmetics by gas chromatography - mass spectroscopy (GC-MS).This method is not applicable to the detection and/or quantification of DEA-related ingredients. When this method is used to analyse unfamiliar sample matrices analysts are advised to confirm the applicability and flexibility of the techniques in their matrix.Under the conditions specified this method is reliable for quantification with DEA level at 1 000 mg/kg (0,1 %).However, samples with lower concentrations (<0,1 %) or otherwise unusual compositions or characteristics can present difficulties (such as, for example, peak tailing) that preclude the direct use of this method.Cross References:ASTM D7599 - 09SN/T 2107-2008All current amendments available at time of purchase are included with the purchase of this document.
