Abstract
A new method of analysis was proposed based on the use of permselective membrane which gives the possibility of enriching and analyzing trace volatile organics in waters. A silicone membrane introduction device which is simple and easy to construct was designed to couple with JMS-D300 Mass Spectrometer. A quantitative formula which is available in the Membrane Introduction Mass Spectrometry was deduced. This paper studied the determination of alkanes, aromatic compounds and halogenated organics in waters by MIMS and discussed the effects of equilibrium time, temperature, sample volume, sample matrix etc. on responses of analyzed components. It was found that 22 volatile organics presented a wide linear concentration range from ppb to ppm, detection limits from 0.1 to 10 ppb and recoveries from 90% to 110%.
