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。
The sample injector is used to inject the sample in to the HPLC system. To realize appropriate elution, the sample is Typically dissolved in an appropriate solvent that matches the cell section.
Column challenges: A soiled or weakened column can cause peak broadening. Contaminants can accumulate on the column after some time, hindering analyte separation. Frequently thoroughly clean the column based on the producer's instructions. If cleansing does not support, look at replacing the column.
Compatibility: The solvent shouldn't respond Together with the analytes or degrade the sample matrix. Consult with protection knowledge sheets (SDS) for compatibility information.

Peak locations: The area underneath Each and every peak from the chromatogram is proportional to the amount of analyte present, making it possible for for quantification.
규제 약물(마약, 합성 마약, 대마, 각성제, 향정신성 의약품, 아편양제제 등), 반도핑 관련(금지 물질, 금지 약물, 스테로이드 등), 약물 대사물
測定時間は測定物質および測定パラメータによって大きく変動するが、一般的には数分から数十分/回程度である。
Polarity: The polarity of your cell phase considerably influences separation. A more polar cell stage interacts additional strongly with polar analytes, resulting in them to elute (exit the column) slower than significantly less polar analytes.
移動相としては、カラムや装置に悪影響を与えない範囲で各種の溶媒が使用される。水や塩類の水溶液、アルコール類、アセトニトリル、ジクロロメタン、トリフルオロ酢酸などが用いられる。相溶性のある（互いに混じり合う）溶媒を混合して使用する場合が多い。
In liquid–liquid chromatography the stationary period is often a liquid film coated on the packing substance, ordinarily 3–ten μm porous silica particles. Because the stationary stage may very well be partly soluble in the cell phase, it might elute, or bleed with the column after some time.
It really is essential for laboratory personnel to realize a basic comprehension of HPLC just before applying it to analyze compounds accurately and make certain responsible success.
are made by reacting the silica particles using an organochlorosilane of the read more final variety Si(CH3)2RCl, the place R is an alkyl or substituted alkyl group.
The injector is positioned once the pump to introduce the sample to the cell period. Syringes are the most regular sample injectors. From the auto-injector, injection of your sample takes place mechanically read more at the predetermined time.
