크로마토그래피 원리의 큰 틀도 마찬가지로 두 상에 대한 분배 차이를 이용하여 분석물을 분리, 정제할 수 있습니다. 다만 크로마토그래피에서 두 개의 상은 하나는 고정하고 다른 하나는 일정 방향으로 이동시켜 사용합니다.

High-Performance Liquid Chromatography (HPLC) is a sophisticated analytical approach according to chromatographic ideas of separation and interaction in between substances and stationary and cell phases.
The selection with the column type is determined by the physicochemical Homes with the analytes being separated.
-hydroxybenzoic acid—on the nonpolar C18 column working with an aqueous buffer of acetic acid and sodium acetate as being the mobile phase. The retention times for these weak acids are shorter when employing a fewer acidic cell period because Every solute is present within an anionic, weak foundation variety which is a lot less soluble within the nonpolar stationary section.
The column is full of a stationary section product. The choice of column and stationary period website relies on the character on the compounds being analyzed plus the separation aims.
The pump is the guts with the HPLC system. It provides the mobile phase at a continuing and high stress (around 400 atm) through the column. Reliable circulation amount is significant for acquiring best separation and protecting reproducibility. Variables to look at when selecting a move level incorporate:
Different types of detectors used in HPLC are refractive index detectors, UV detectors, and fluorimetry detectors.
移動相としては、カラムや装置に悪影響を与えない範囲で各種の溶媒が使用される。水や塩類の水溶液、アルコール類、アセトニトリル、ジクロロメタン、トリフルオロ酢酸などが用いられる。相溶性のある（互いに混じり合う）溶媒を混合して使用する場合が多い。
이 두 용매는 혼합되지 않기 때문에 분액깔대기에 각각 동량을 넣어 혼합하려고 해도 바로 물층과 기름충, 이렇게 두 개의 상으로 분리됩니다. 여기에 다른 성분이 첨가되어 혼합되면 분석물질은 어느 쪽 상에 존재할까요?
現在では分析物の注入から検出・定量までを一体化して自動的に行えるようにした装置を用いて、再現性の高い分析が比較的簡便に行える。分析化学や生化学で頻繁に用いられ、俗に「液クロ」（液体クロマトグラフィーの略）といえばこれを指すことが多い。
HPLC is a improved type of column click here chromatography. The real difference is, here rather than dripping solvent beneath gravity a strain of approximately 400 atmosphere is used to the chromatography to have a quick separation.
The separation of the person components during the mixture normally takes position within the stationary section while in the column. As opposed to the glass column, it is prepared in chrome steel.
