Title: Determination of n-Propanol in Air of Workplace by Gas Chromatography
Abstract: Objective To establish a gas chromatographic method for the determination of n-propanol in the air of workplace.Methods The air samples were collected with activated carbon tubes and desorbed with 1% isopropanol in carbon disulfide,the target toxicant was separated with capillary column and detected with flame ionization detector,qualified by retention time and quantified by peak area.Results The linear range of n-propanol in air of workplace was 80.36-1 607 μg/ml,the correlation coefficient was 0.999 8.The limit of detection was 4.5 μg/ml.The limit of quantity was 15.0 μg/ml.The minimal detected concentration was 3.0 mg/m3 in the condition of 1.5 L sampling volume and 1ml desorbed volume.Relative standard deviation was 0.64%-1.74% and the rate of recovery was 93.7%-96.9%.Conclusion The developed method reveals high sensitivity,precision and accuracy,and is applicable to the determination of n-propanol in the air of workplace.
