To establish a gas chromatographic method for detecting 2-butoxy ethanol in the air of workplaces.


After the air samples were collected with activated carbon tubes and desorbed with methylene chloride/methanol, the target toxicant was separated with FFAP capillary columns and detected with flame ionization detector, qualified by retention time and quantified by peak area.


The linear range of 2-butoxy ethanol in air of workplace was 56.3 ∼ 901.0 µg/ml, the correlation coefficient was 09999. The limit of detection was 2.0 µg/ml. The limit of quantity was 5.0 µg/ml. The minimal detecting concentration was 0.27 mg/m(3) in the condition of 7.5L sampling volume and 1ml desorbed volume. Relative standard deviation was 3.04% ∼ 7.93% and the recovery was 92.7% ∼ 95.5%.


In present study the detecting method with high sensitivity, precision and accuracy can be used to determine 2-butoxy ethanol in the air of workplaces.
