ISO 18857-2:20 09规定了气相色谱-质谱（GC？MS）测定饮用水、地下水、地表水和废水的非过滤样品中选定的烷基酚、它们的乙氧基化物和双酚A。相萃取和衍生化。工作范围的下限取决于基质、待分析的特定化合物和质谱检测单元的灵敏度。该方法适用于4-（1，1，3，3-四甲基丁基）苯酚（OP）及其单（OP1EO）和二乙氧基化物（OP2EO）的工作范围为0,005 μ g/l至0.2 μ g/l，4-壬基苯酚（异构体混合物）（NP）及其单（NP1EO）和二乙氧基化物（NP2EO）的工作范围为0.03 μ g/l至0.2 μ g/l，双酚A（BPA）的工作范围为0.05 μ g/l至0.2 μ g/l。取决于基质，该方法还适用于OP、OP1EO、OP2EO和BPA的工作范围为0.1 μ g/l至50 μ g/l，以及NP、NP1EO和NP2EO的工作范围为0.5 μ g/l至50 μ g/l的废水。工作范围基于耐用性测试中进行的实验工作。通过使100mL样品通过筒提取含有浓度超过500mg/l的悬浮物的水样和废水样品。
ISO 18857-2:2009 specifies a gas chromatographic-mass spectrometric (GC？MS) determination of selected alkylphenols, their ethoxylates and bisphenol A in non-filtered samples of drinking, ground, surface, and waste waters following solid？phase extraction and derivatisation.The lower limit of the working range depends on the matrix, on the specific compound to be analysed and on the sensitivity of the mass spectrometric detection unit. The method is applicable in a working range from 0,005 μg/l to 0,2 μg/l for 4-(1,1,3,3-tetramethylbutyl)phenol (OP), and its mono- (OP1EO) and diethoxylate (OP2EO), from 0,03 μg/l to 0,2 μg/l for 4-nonylphenol (mixture of isomers) (NP), and its mono- (NP1EO) and diethoxylate (NP2EO), and from 0,05 μg/l to 0,2 μg/l for bisphenol A (BPA).Depending on the matrix, the method is also applicable to waste water in a working range from 0,1 μg/l to 50 μg/l for OP, OP1EO, OP2EO and BPA, and from 0,5 μg/l to 50 μg/l for NP, NP1EO and NP2EO. The working ranges are based on experimental work carried out in ruggedness testing. Water samples containing suspended matter at concentrations of more than 500 mg/l and waste water samples are extracted by passing a 100 ml sample through the cartridge.
