标准摘要
[中文适用范围]： 该方法包括将气态测试部分通过水以吸收丙酮、乙腈、2-丙醇和甲醇，随后使用氢火焰离子化检测器对水溶液进行气相色谱分析，并将获得的峰与这些峰进行比较。 源自外部标准。 本方法适用于丙酮、2-丙醇、甲醇浓度大于1mg/kg，乙腈浓度大于10mg/kg的产品。 [外文原描述]： The method comprises the passage of a gaseous test portion through water to absorb acetone, acetonitrile, propan-2-ol and methanol, and subsequent gas chromatographic analysis of the aqueous solution, using a flame ionization detector, and comparison of the peaks obtained with those derived from an external standard. The method is applicable to products having acetone, propan-2-ol and methanol concentrations greater than 1 mg/kg, and acetonitrile concentrations greater than 10 mg/kg.
英文名称Ethylene and propylene for industrial use — Determination of acetone, acetonitrile, propan-2-ol and methanol — Gas chromatographic method
