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.

Ion-exchange: Separates billed molecules dependent on their conversation with billed useful groups over the stationary phase.

. HPLC separation of a combination of flavonoids with UV/Vis detection at 360 nm and, from the inset, at 260 nm. The choice of wavelength has an effect on Every analyte’s signal.

Recording and analyzing information is essential for interpreting the results of an HPLC experiment. By researching the chromatogram, analysts can establish and quantify the parts in a combination and evaluate the achievement in the separation.

物質にエネルギーを与える（励起）ことにより発光する（蛍光）性質を利用した検出器。一般に選択性が高く高感度で、物質に特異的な検出が可能。蛍光する性質を持たない物質については、その物質を標識することにより検出が可能になる。

, one example is, has two cell period reservoirs which have been used for an isocratic elution or simply a gradient elution by drawing solvents from a person or the two reservoirs.

The concentration of caffeine in beverages is decided by a reversed-period HPLC separation using a cellular stage of 20% acetonitrile and eighty% water, and employing a nonpolar C8 column. Outcomes for click here a number of 10-μL injections of caffeine standards are in the following desk.

Regular-period: Separates according to polarity. Analytes with higher polarity interact additional Along with the polar stationary section and elute later on.

The cell period’s circulation charge is set because of the combined speeds of The 2 pumps. By shifting the relative speeds of the two pumps, various binary cell phases is often well prepared.

It really is important for laboratory staff to get a essential idea of HPLC ahead of applying it to research compounds properly and read more be certain reliable outcomes.

Column assortment: The stationary stage inside the column interacts with analytes. Utilizing the Completely wrong column chemistry may result in inadequate resolution. Consider using a different column which has a stationary period that provides far better selectivity for the analytes.

The injector introduces a specific quantity on the sample Remedy in the cellular section stream. Numerous injection techniques exist, with loop injection getting a common method.
