<TEX>$85{\mu}m$</TEX>-polyacrylate(PA) 와 <TEX>$100{\mu}m$</TEX>-polydimethylsiloxane(PDMS) fiber를 사용하여 물증의 DBCP와 n-butylbenzene을 추출한 후 GC-MS로 분석하는 방법을 연구하였다. SPME 과정에 영향을 미치는 인자들, 즉 추출 시간, 주입 길이, 주입 온도, 탈착 시간 및 탈착 온도들에 대한 최적화 조건을 조사하였다. 검량선의 직선성(correlation coefficient, R)은 0.99 이상이었으며, 본 분석법의 검출한계는 1.5 와 <TEX>$10.8{\mu}g/L$</TEX> 이었고, 분석법의 재현성은 RSD 10.4와 14.4 % 였다.
Solid phase microextraction(SPME) with <TEX>$85{\mu}m$</TEX>-polyacrylate (PA) and <TEX>$100{\mu}m$</TEX>-polydimethylsiloxane(PDMS) fibers, coupled to gas chromatography-mass spectrometry was used to determine 1,2-dibromo-3-chloropropane(DBCP) and n-butylbenzene in water. The conditions affecting the SPME process(i.e, extraction time, injection length, injection temperature, desorption time and temperature) were optimized. The linearity of the calibration curve (correlation coefficient, R) was over 0.99 and the limits of detection of the method were between 1.5 and <TEX>$10.8{\mu}g/L$</TEX>. Repeatability of the method was between 10.4 and 14.4 %.
