Abstract
The solid phase microextrction (SPME) fiber which contains $100{\mu}m$ polydimethyl siloxane of a stationary phase was used for the analysis of volatile organic compounds contained in aqueous solution. sixteen volatile organic compounds, which were spiked in blank water and extracted by the headspace SPME techique, were analyzed by gas chromatography/mass spectrometry (GC/MS). Analytical results showed that the percent of average recoveries and relative standard deviations were 97% and 4.7%, respectively. The value of detection limit was ranged from 0.01 to $0.5{\mu}g/l$. These results are more accurate than those obtained by the other methods such as purge and trap and headspace methods.
16종의 휘발성 유기화합물을 blank water에 첨가하고 고정상으로 $100{\mu}m$ polydimethyl siloxane을 입힌 solid phase microextraction(SPME) fiber를 사용하는 headspace SPME방법으로 추출하여 gas chromatography/mass spectrometry (GC/MS)로 분석하였다. 이 방법의 평균회수율은 97%, 평균상대표준편차는 4.7%, 그리고 검출한계는 $0.01-0.5{\mu}g/l$를 나타냈다. 즉 SPME 방법을 이용한 수용액 중의 휘발성 유기화합물의 결과는 현재 많이 사용되고 있는 기존의 다른 방법보다 우수하고 편리한 방법으로 나타났다.
