HH-1 Capillary Column Determination of HeptaFU, IsoFU and EnFU in Workplace Air by Gas Chromatography
Detailed information of gas chromatographic determination method of heptaFU alkane, isoFU alkane and EnFU alkane in the air of HH-1 capillary column workplace:
Name: capillary column
Stationary phase: dimethylpolysiloxane
Specification: 30m * 0.32mm * 1.0um
Model: HH-1
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for the determination of heptafluorowan, isofuane and enflurane in the air of workplaces by solvent desorption gas chromatography Methods The heptafulane, isofulane and enfurane in the air were collected by activated carbon tube, desorbed by dichloromethane, and separated by capillary chromatography with dimethylsiloxane (hh-1) Results The mass concentrations of heptafuane, isofuane and enfurane in this method were 1.9~304.8 μ g/ml、2.1~300.4 μ G/ml and 1.7~305.2 μ The linearity is good within the range of g/ml, the correlation coefficient is greater than 0.999, and the detection limits are 0.6, 0.6 and 0.5 respectively μ G/ml, lower limit of quantification is 1.9 respectively μ g/ml、2.1 μ G/ml and 1.7 μ G/ml, the low detectable mass concentration of method zui is 0.1, 0.2 and 0.1 mg/m respectively (3 calculated according to 4.5 L of collected air sample); The relative standard deviations of heptafuane, isofuane and enfurane are 2.5%~3.0%, 2.3%~3.1% and 2.2%~3.0% respectively; The average desorption efficiency was 101.1%~103.3%, 100.7%~102.7% and 101.0%~102.9% respectively; The penetration capacities of heptafuane, isofuane and enfurane are more than 3.7 mg, 3.4 mg and 3.4 mg respectively (100 mg activated carbon); The sampling efficiency is; The sample can be stored at room temperature for at least 10 d. Conclusion This method has low detection limit, high accuracy and good precision, and is suitable for the determination of heptafuane, isofuane and enfurane in the air of workplace
