Abstract

Benfuresate의 잔류분석을 위해 GC-FPD(S-mode)를 이용하여 분석조건을 설정 중 열적 불안정으로 인해 열분해 산물과 모 화합물이 혼재됨이 확인되었다. 가스크로마토그라프를 이용한 열분해의 주된 요인은 주입구의 온도와 주입구내의 기화 정도인 것으로 판단되었으며, 주입구를 Chauhan과 Debre 가 고안한 on-column으로 교체 후 분석한 결과 분해산물이 없는 단일 봉우리의 크로마토그램을 얻을 수 있었고, 절대량으로 0.6-4ng의 정량 범위 내에서 유의성 높은 검량선을 얻을 수 있는 주입구 온도는 20$0^{\circ}C$였다.
