수용액상에 존재하는 3-monochloropropane-1,2-diol (3-MCPD)의 LC-MS를 이용한 분석방법을 개발하였다. 수용액 시료에 수산화나트륨 용액을 첨가하여 강알칼리 상태를 유지시킨 후, 3-MCPD의 유도체화를 위하여 benzoyl chloride <TEX>$25{\mu}L$</TEX>을 넣어 직접 반응시켰다. 반응 후 유도체를 pentane으로 추출하여 LC-MS의 selected ion monitoring (SIM) 법으로 정량하였다. 분석결과 검량선은 <TEX>$1.0-100{\mu}g/mL$</TEX> 농도범위에서 <TEX>$r^2
The analysis method of 3-Monochloropropane-1,2-diol (3-MCPD) compound in water was developed using liquid chromatography with mass spectrometric detection. Aqueous solution was controlled in strong basic condition with sodium hydroxide, and then <TEX>$25{\mu}L$</TEX> of benzoyl chloride was added to the solution for the derivatization of 3-MCPD. The derivative was extracted using pentane and analyzed by the selected ion monitoring (SIM) method of LC-MS. The results of analyses showed that the calibration curves was in the range of 1.0 to <TEX>$100{\mu}g/mL$</TEX> with a good linearity (correlation coefficient of <TEX>$r^2
