ISO 18857-2:2009规定了在固体相萃取后，未过滤的饮用水，地面，表面和废水样品中选择的烷基酚，它们的乙氧基化物和双酚A的气相色谱 - 质谱（GC-MS）测定和衍生化。 工作范围的下限取决于基质，要分析的具体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）和其单（OP1EO）和二乙氧基化物（OP2EO）的工作范围为0,005μg/ l至0.2μg/ l ），4-壬基苯酚（异构体混合物）（NP）和其单（NP1EO）和二乙氧基化物（NP2EO）的0,03μg/ l至0.2μg/ l，以及0.05μg/ l至双酚A（BPA）的0.2μg/ l。 根据基质，该方法也适用于OP，OP1EO，OP2EO和BPA的工作范围为0.1μg/ l至50μg/ l的废水，以及0.5μg/ l至50μg/ NP为NP，NP1EO和NP2EO。工作范围是基于在耐用性测试中进行的实验工作。通过将100ml样品通过滤筒，提取含有浓度超过500mg/l的悬浮物和废水样品的水样

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.
