Abstract:
OBJECTIVETo develop determination of dimethyl ether in workplace air by GC.
METHODSDimethyl 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.
RESULTSThere was a good linearity (r = 0.9999) over the concentration of 0-63.91 microg/L, detection limit can reach 0.75 microg/ml.
CONCLUSIONThis method proved to be accurate and sensitive, to meet the determination of the dimethyl ether in workplace air.
