3 1. HPLC 의 역사 ; Mikhail Tswett Separates Plant Pigments on Chalk Columns 1970년 이전 ; few reliable chromatographic methods 1970’년대 ; open-column chromatography, paper chromatography, and thin-layer chromatography => similar compounds pressure liquid chromatography => flowthrough/purification times by column chromatogaphy. Pump Technology (constant flow rate or constant pressure) 1970년대 중반 : High pressure liquid chromatography, column packing materials and the on-line detectors => Performance I970년대 후반 reverse phase liquid chromatography => very similar compounds. 1980년대 이후 ; 대부분의 chemical compounds 분리. New techniques=> Computers and automation, typical column(250 mm L, 3-5 mm ID) => micro/capillary columns(1-2mm ID, 3 µm-300 µm ID), affinity/chiral columns and Fast HPLC(Length 3-5mm, smaller particles size10, 5, 3um), optimal analysis ; various types of columns, a variety of detectors of the compound. 2000년대 ; GLP, UHPLC(Sub 2um), MSMS,… Quantitaton/Qualification,… Prep,… 응용영역 : biotechnological, biomedical, biochemical research, pharmaceutical industry, cosmetics, energy, food, and environmental industries,…

6 3. 컬럼의 분리 단 분배계수 KA = [A]u phase/[A]l phase
KA = [A]sol phase/[A]lliq phase

7 Column의 구조의 활용 Vt = Vo + Ve Tubing Frit 분리관 Vt는
GPC/GFC의 경우 V의 약 75-80% HPLC의 경우 V의 약 60-65% 안정화 부피 : Vt 의 10-20배 이상 시료 주입량 : Vt 의 % 이하 시료 농도 : 시료 주입량의 0.I -10% 이하 충전물
