标准范围

该方法包括将气体试验部分穿过水中，以吸收丙酮、乙腈、丙醇和甲醇，随后使用火焰离子化检测器对水溶液进行气相色谱分析，并将获得的峰与来自外部标准的峰进行比较。该方法适用于丙酮、丙醇和甲醇浓度大于1 mg/kg，乙腈浓度大于10 mg/kg的产品。

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.
