Determination of Enflurane in Workplace Air by Gas Chromatography
Details of gas chromatography method for determination of enflurane in the air of workplace:
Name: capillary column
Statio
nary phase: 100% dimethylpolysiloxane
Specification: 30m * 0.32mm * 1.0um
Model: HH-1
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a solvent desorption gas chromatographic method for the determination of enflurane in the air of workplaces. Methods The experiment was carried out according to the requirements of the Research Standard for the Detection Methods of Toxic Substances in the Air of Workplace. Results The method was applied in l ~ 7480 μ The range of g/ml is linear; The sample can be stored in the carbon tube at room temperature for at least 7 days; The reproducibility of the method is good, and the relative standard deviation of different co
ncentrations is 0.5% ~ 1.3%; The minimum detection limit of the method is 1.0 μ g/ml; The average desorption efficiency was 97.0%~103.8%; The sampling efficiency is 94.9%~100.0%; The penetration capacity of 100 mg activated carbon to enflurane is 3.7 mg; The coexistence of sevoflurane, isoflurane and ethanol with enflurane in the air does not interfere with the determination under the co
nditions of this method. Co
nclusion All the indexes of the method meet the requirements of the Research Standard for the Detection of Toxic Substances in the Air of Workplace, and it is suitable for the field mo
nitoring of enflurane in the air of workplace.
