ディテクター（検出器）としては目的とする物質の性質に応じて光学的性質（吸光度、屈折率、蛍光等）、電気化学的性質、質量分析法などを利用する装置がある。
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。

Bubbling an inert gasoline in the mobile section releases risky dissolved gases. This method is termed sparging.
. Illustration of a normal high-performance liquid chromatograph with insets demonstrating the pumps that transfer the cell stage with the system as well as the plumbing utilized to inject the sample into the mobile section.
이러한 특징으로 고성능 액체 크로마토그래피는 전 세계 모든 과학 분야 및 산업의 기반을 뒷받침하는 과학기술로서의 위치를 확립하고 있습니다.
규제 약물(마약, 합성 마약, 대마, 각성제, 향정신성 의약품, 아편양제제 등), 반도핑 관련(금지 물질, 금지 약물, 스테로이드 등), 약물 대사물
高速液体クロマトグラフィーにおいては各物質は比較的鋭いピークとして検出され、分離（他の物質のピークと明確に分けられる）および検出（鋭いピークにより高い感度が得られる）の能力が従来の液体クロマトグラフィーより良くなる。
The fast and productive setting up of the column might take many check here years to learn. Here are a few strategies and methods to create the right column
). Should the detector is often a diode array spectrometer, then we also can Exhibit The end result as a three-dimensional chromatogram that exhibits absorbance for a how HPLC works function of wavelength and elution time.
Conversely, a move fee that may be way too reduced could cause excessive band broadening. Check out your circulation charge settings and change them according to the established process.
There are several selections for checking the chromatogram when utilizing a mass spectrometer as the detector. The most typical system should be to constantly scan your complete mass spectrum and report the entire signal for all ions reaching the detector throughout each scan. This whole ion scan supplies common detection for all analytes. As noticed in Figure twelve.5.fourteen
, for example, has two mobile period reservoirs which have been useful for an isocratic elution or maybe a gradient elution by drawing solvents from one or equally reservoirs.
Lowering the level of acetonitrile and rising the level of drinking water while in the cell will improve retention moments, offering far more time for you to outcome a separation.
