Standard Number: HJ 1289-2023(HJ1289-2023)
Chinese:土壤和沉积物 15种酮类和6种醚类化合物的测定 顶空/气相色谱-质谱法
English:Determination of 15 ketones and 6 ethers in soil and sediment Headspace/gas chromatography-mass spectrometry
Effective Date:2023-08-01
Standard Applicability:This standard specifies a headspace/gas chromatography-mass spectrometry method for the determination of 15 ketones and 6 ethers in soil and sediment. This standard applies to the determination of 15 ketones and 6 ether compounds in soil and sediment, such as ether, acetone, methyl tert-butyl ether, diisopropyl ether, ethyl tert-butyl ether, 2-butanone, methyl tert-pentyl ether, 2-pentanone, ethyl tert-pentyl ether, 3-pentanone, methyl tert-butyl ketone, 4-methyl-2-pentanone, 2-hexanone, cyclopentanone, 3-heptanone, 2-heptanone, cyclohexanone, 6-methyl-2-heptanone, diisobutyl ketone, 3-octanone, 2-octanone, 3-octanone, 2-octanone, 15 ketones and 6 ethers. When the sample volume is 2.0 g, the headspace bottle volume is 22 ml and the volume of saturated sodium chloride solution is 10 ml, the detection limits of the method for the 15 ketones and 6 ethers are 0.1 mg/kg-2 mg/kg, and the lower limits of the method are 0.4 mg/kg-8 mg/kg.
