[Determination of dimethyl ether in workplace air with gas chromatography].


PMID 22808552

Abstract

To develop determination of dimethyl ether in workplace air by GC. Dimethyl ether were sampled with solvent desorption active carbon tube. The sampled carbon tube were desorbed by carbon tetrachloride, Elite-WAX column was used with temperature programmed from 40 to 90 degrees C, and the carrier gas programmed from 1.4 - 2.5 ml/min. There was a good linearity (r = 0.9999) over the concentration of 0-63.91 microg/L, detection limit can reach 0.75 microg/ml. This method proved to be accurate and sensitive, to meet the determination of the dimethyl ether in workplace air.
