Method 84

2-Butanone (MEK) by GC/FID


This method describes the sample collection and analysis of 2-butanone (MEK). Samples are collected by drawing air through glass sampling tubes containing Carbosieve S-III (carbon based molecular sieve) adsorbent. Samples are desorbed with a mixture of 99/1 (v/v) carbon disulfide (CS2)/dimethylformamide (DMF) in the presence of anhydrous sodium sulfate and are analyzed by GC using a flame ionization detector.
