The method was established for determination of nine ester compounds in water by gas chromatography-mass spectrometry with purge and trap.The sensitivity of method was improved by increasing sodium sulfate quantity.Purge and trap obtained the highest efficiency when sodium sulfate became supersaturate.Calibration curves exhibited good linearity in certain concentration.Detection limits ranged from 0.14 μg/L to 0.25 μg/L.RSD of simulation duplicated samples ranged from 0.6% to 1.8%.The spiked… CONTINUE READING
