ABSTRACT
<p><b>OBJECTIVE</b>To establish a method for determination of N-isopropylaniline in the workplace atmosphere by gas chromatography.</p><p><b>METHODS</b>Air samples were collected by silica gel tube and desorbed by acetone. Then they were separated through DB-WAX columns and N-isopropylaniline was determined by flame ionization detector.</p><p><b>RESULTS</b>The concentration of N-isopropylaniline showed a good linear relationship within the range of 1.40∼665.0 µg/ml. The sampling efficiency was 100%. The accuracy was 96%∼ 99% and the precision was 2.1%∼7.0%. The minimum detectable concentration was 0.056 mg/m(3) (with sampled air volume of 7.5 L).</p><p><b>CONCLUSION</b>The method meets the requirements of analysis and applies to the determination of N-isopropylaniline in the workplace atmosphere.</p>
