Abstract
 RP-HPLC에서 머무름을 주도하는 중요한 요인 중의 하나인 소수성효과에 대한 온도와 용매의 영향을 알아보았다. 용량계수가 1일 때의 유기 용매의 부피분율으로 나타낸 소수성 지표 φ0를 사용하여 머무름 거동을 설명하는 것이 이전까지 주로 사용되던 logkw' 또는 S 지표값을 이용한 설명보다 더 특성적이고 명확한 결과를 얻을 수 있었다.

Hydrophobic effect as an important role of retention mechanism has been examined through composition change in mobile phase(60∼80%) using two kinds of modifier(MeOH, ACN) over the temperature ranging from 5℃ to 55℃ in RP-HPLC. By observing retention behavior, it can be seen that the hydrophobicity index φ0 is more characteristic and reasonable when compared with the another hydrophobicity index, logkw' or S index.
