Scope
Scope: This standard specifies the headspace solid-phase microextraction-gas chromatography-mass spectrometry method for the simultaneous determination of 11 odor substances, including 2-methylisoeugenol, geosmin, 2-isopropyl-3-methoxypyrazine, 2-isobutyl-3-methoxypyrazine, 4-chlorobenzoic acid, 2,4,6-trichlorobenzoic acid, 2,4,6-tribromobenzoic acid, 2-tert-butylphenol, 4-tert-butylphenol, 4-butylphenol, and 2,4-ditert-butylphenol in surface water, groundwater, and drinking water. This standard is applicable to the determination of 2-methylisoeugenol, geosmin, 2-isopropyl-3-methoxypyrazine, 2-isobutyl-3-methoxypyrazine, 4-chlorobenzoic acid, 2,4,6-trichlorobenzoic acid, 2,4,6-tribromobenzoic acid, 2-tert-butylphenol, 4-tert-butylphenol, 4-butylphenol, and 2,4-ditert-butylphenol in surface water, groundwater, and drinking water. After enrichment of water samples using an automatic solid-phase microextraction device, the detection limits of this method are 0.83 ng/L to 24.8 ng/L when the sample volume is 10.0 mL, and the quantification limits are 3.32 ng/L to 99.2 ng/L.
