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.

試料を注入する部分で、手動式（マニュアルインジェクター）と自動式（オートインジェクター）がある。
システムとしてポンプ、インジェクター、ディテクターまでを一貫して製造しているメーカーを挙げる。
The choice in the column style is dependent upon the physicochemical Houses in the analytes being separated.
-hydroxybenzoic acid—with a nonpolar C18 column employing an aqueous buffer of acetic acid and sodium acetate given that the cell section. The retention situations for these weak acids are shorter when employing a much less acidic mobile phase due to the fact Just about every solute is current in an anionic, weak base kind that is definitely fewer soluble during the nonpolar stationary stage.

Add a known quantity of the antidepressant protriptyline, which serves as an inside standard, to each serum sample and to each exterior normal. To get rid of matrix interferents, move a 0.five-mL aliquot of each serum sample or conventional via a C18 reliable-stage extraction cartridge. After washing the cartridge to check here eliminate the interferents, elute the remaining constituents, including the analyte and The interior regular, by washing the cartridge with 0.
Modifying the cellular period’s polarity index adjustments a solute’s retention aspect. As we learned in Chapter twelve.3, even so, a transform in k isn't an efficient way to enhance resolution in the event the First value of k is greater than ten.
Usual-phase: Separates according to polarity. Analytes with higher polarity interact extra Together with the polar stationary stage and elute later.
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?
In a very gasoline chromatograph the force from the compressed gasoline cylinder is sufficient to here press the cell phase throughout the column. Pushing a liquid mobile stage by way of a column, nevertheless, takes a terrific offer additional effort and hard work, making pressures in excess of many hundred atmospheres.
Soon after loading the sample, the injector is turned for the inject position, which redirects the cellular stage through the sample loop and on to the column.
Movement charge troubles: Stream amount instantly has an effect on peak condition. A move rate that's as well high can result in broader peaks as a result of a lot less conversation amongst analytes plus the stationary stage.
