Abstract
|
|
|
|
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.
