OBJECTIVE: To develop determination of dimethyl ether in workplace air by GC.
METHODS: 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.
RESULTS: 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.
CONCLUSION: This method proved to be accurate and sensitive, to meet the determination of the dimethyl ether in workplace air.
