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。
. HPLC separation of a combination of flavonoids with UV/Vis detection at 360 nm and, inside the inset, at 260 nm. The selection of wavelength impacts Just about every analyte’s signal.
Remember, consulting your instrument guide and also the producer's specialized guidance can also be worthwhile assets when troubleshooting particular troubles with your HPLC system.
The three red circles are binary cell phases made by combining equal volumes of the pure cell phases. The ternary cellular period shown from the purple circle incorporates all 3 of the pure mobile phases.
. From the load situation a sample loop—which is out there in a variety of measurements starting from 0.5 μL to 5 mL—is isolated from the cell section and open on the environment. The sample loop is crammed employing a syringe having a ability numerous occasions that with the sample loop, with excess sample exiting with the waste line.
The combination is separated working with The fundamental theory of column chromatography and after that discovered and quantified by spectroscopy. A pc analyzes the data display the output in display.
The running force in an HPLC is adequately high that we are unable to inject the sample in to the mobile period by inserting a syringe via a septum, as is achievable in gasoline chromatography. Instead, we inject the sample employing a loop injector
The buy of elution of compounds from the column is governed from the depth of contact with the stationary section. The eluent Together with the separated check here substances flows previous the detector.
충전제는 실리카겔 혹은 중합체의 미세입자로 표면에 화학 수식이 되어 있는 경우가 대부분이며 여러 종류가 있습니다.
The cellular phase flows throughout the stationary phase and carries the factors of the combination with it. Different factors travel at various rates. Consequently the components divided and found in several region in chromatography to individual, establish and quantify.
Degassing is completed in various means, but the commonest are using a vacuum pump or sparging with the inert gasoline, for example He, which has a reduced solubility more info inside the mobile phase. Particulate components, which may clog the HPLC tubing or column, are removed by filtering the solvents.

The injector is positioned following the pump to introduce the sample into the cellular period. Syringes are quite possibly the most normal sample injectors. From the car-injector, injection from the sample takes place instantly at the predetermined time.
