ISO 17283-1:2014规定了通过HPLC法测定表面活性剂中一氯乙酸（一氯乙酸）和二氯乙酸（二氯乙酸）的方法。 该方法适用于阴离子表面活性剂如烷基（苯基）乙氧基化羧酸酯（AEC）或两性表面活性剂，如烷基咪唑啉羧酸酯、烷基二甲基甜菜碱和脂肪乙酰丙基二甲基甜菜碱。 一氯乙酸的检出限（LOD）≤0.3μg/ml，二氯乙酸的检测限≤0.2μg/ml； 一氯乙酸的定量限（LOQ）≤1,0μg/ml，二氯乙酸≤0,75μg/ml（使用标准溶液）。 样品重量为5g时，一氯乙酸的检出限≤6 mg/kg，二氯乙酸的检测限≤4 mg/kg；一氯乙酸和二氯乙酸的LOQ分别为≤20mg/kg和≤15mg/kg。

ISO 17283-1:2014 specifies a method for the determination of monochloroacetic acid (monochloroacetate) and dichloroacetic acid (dichloroacetate) in surfactants by HPLC method. The method applies for anionic surfactants such as alkyl (phenyl) ethoxylated carboxylate (AEC) or amphoteric surfactants such as alkyl imidazoline carboxylate, alkyl dimethyl betaine, and fatty acetyl propyl dimethyl betaine. The limit of detection (LOD) is ≤0,3 μg/ml for monochloroacetic acid and ≤0,2 μg/ml for dichloroacetic acid; the limit of quantification (LOQ) is ≤1,0 μg/ml for monochloroacetic acid and ≤0,75 μg/ml for dichloroacetic acid (using a standard solution). The LOD, at 5 g of sample weight, is ≤6 mg/kg for monochloroacetic acid and ≤4 mg/kg for dichloroacetic acid; and the LOQ is ≤20 mg/kg for monochloroacetic acid and ≤15 mg/kg for dichloroacetic acid.
