일반적으로 해양 퇴적물에서 검출되는 것은 무엇인가? | 전 지구의 해양 퇴적물에서 널리 관측되고 있는 long chain alkyl diols (LCDs)은 De Leeuw et al. (1981)에 의해 흑해(Black Sea) 퇴적물에서 처음 보고되었다. | |
현재까지 보고된 LCDs 분석 방법은 무엇을 주 기반으로 하는가? | 현재까지 보고된 LCDs 분석 방법은 GC-MS를 주 기반으로 한다. 현재까지 분석에 사용된 GC 컬럼은 CP-Sil5CB (e. | |
CP-Sil5CB 컬럼과 HP-5ms, DB-5 컬럼을 이용한 분석결과에 따르면, 세 컬럼에서 분석된 농도 결과 사이에 통계적으로 유의한 차이가 보이는 이유는 무엇인가? | CP-Sil5CB 컬럼과 HP-5ms, DB-5 컬럼을 이용한 분석결과에 의하면 세 컬럼에서 분석된 농도 결과 사이에 통계적으로 유의한 차이가 보였다. 이러한 차이는 컬럼 내부에 코팅된 충진물의 차이 때문인 것으로 추측된다. LDI로 복원된 수온에서도 CP-Sil5CB 컬럼과 HP-5ms, DB-5 컬럼 간에 차이를 나타냈다. |
