HPLC 분리이론 v Resolution : 분리능(Rs) v Retention Time : 머무름 시간(t. R), RT v Selectivity : 선택도(α) v Capacity factor : 분리계수(k´) v Efficiency : 분리효율(N) v (N=Theoretical Plate Number)












Solvent Strength (용매 강도) v 용매강도는 역상, 순상에 따라 서로 반대의 강도를 가지며, 유기용매와 물의 혼합시 물의 함량이 많을수록 성분의 머무름 시간(Retention Time) 은 길어짐. Solvent Strength Reversed Phase Normal Phase Water DMSO Methanol Acetonitrile Tetrahydrofuran Haxane 1 -Chlorobutane Methylene Chloride Acetonitrile
