Name: Agilent 7820A glass column

Specifications: 2m*1/4, 80-100 mesh

Model: 1.5%OV-17+1.95%OV-210/Chromosorb AW DMCS-HP (80-100 mesh)

Number: 20220818002

Temperature: 240°C

Application: GB/T 14550-2003 Gas chromatographic method for determination of hexahexahexanol and DDT in soil


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a rapid solvent extraction-gas chromatography-mass spectrometry method for the simultaneous determination of polycyclic aromatic hydrocarbons, hexahexahexanol and DDT in soil. The extraction solvent and elution solvent were optimized, and the soil samples were treated by accelerated solvent extraction method. The extraction solvent was dichloromethane-n-hexane (1∶1). The extract was concentrated with a nitrogen blowing apparatus, purified by a magnesium silicate solid phase extraction cartridge, and the solid phase extraction cartridge was activated and eluted with a mixed solvent of dichloromethane-n-hexane (3:7), and the effluent was purified by nitrogen blowing. It was concentrated to 1 mL and analyzed and quantified by gas chromatography-mass spectrometry internal standard method. The linearity of the eight organochlorine pesticides was good in the range of 5.0~500μg/L, the detection limits of the method were 0.000 55~0.000 77 mg/kg, the recoveries were 68.2%~112.7%, and the relative standard deviations were 4.3%~10.1% (n=5). This method can be used to simultaneously determine the content of hexahexahexanol and DDT in soil.
