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.
内部にカラムを収納して加熱あるいは冷却を行い、カラムの温度を制御する装置。カラムヒーターとも称する。
전자를 '고정상', 후자를 '이동상'이라 부르며 크로마토그래피에서는 분석자는 고정상과 이동상의 조합에 의해 분석물의 분리를 제어할 수 있게 됩니다.따라서 분석물, 고정상, 이동상, 세 가지 특성의 이해가 크로마트그래피에서 매우 중요합니다.
, which permits us to examine a broad selection of cell phases with only 7 experiments. We begin by changing the quantity of acetonitrile during the mobile section to create the absolute best separation inside the desired Assessment time.
. Solvent triangle for optimizing a reversed-period HPLC separation. The a few blue circles present cell phases consisting of the natural and organic solvent and water.
An internal common is necessary when making use of HPLC–MS since the interface in between the HPLC plus the mass spectrometer won't let for your reproducible transfer in the column’s eluent into your MS’s ionization chamber.
It's really a measure of the speed at which a drug is removed from your body.

The data acquisition system data and processes the indicators within the detector, making it possible read more for with the creation of chromatograms as well as the quantification of compounds.
A pump forces a solvent by way of a column less than high pressures of around four hundred atmospheres. The column packing material or adsorbent or stationary stage is usually a granular materials of sound particles for instance silica or polymers.
The overarching basic principle of HPLC is chromatography. It really is a technique for separating chemical substances dependent on their differential interactions which has a stationary phase and a cellular stage.
The pressurized liquid is typically a mixture of solvents which include water, acetonitrile and/or methanol and is also often called the cellular period.
특히 컬럼의 선정은 분석의 결과에 영향을 미치기에 신중하게 선택하여야 합니다.
, which is the greater frequent method of HPLC, the stationary stage is nonpolar as well as mobile stage is polar. The most typical nonpolar stationary phases use an organochlorosilane wherever the R group can be an n
