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。
최상의 결과를 위해서는 올바른 시약을 사용함으로써 피크 대칭성을 개선할 수 있습니다.
a values, the pH of your cellular stage has another effect on Each and every solute’s retention time, making it possible for us to discover the optimum pH for effecting a whole separation of the 4 solutes.
物質の電気化学的な性質を利用した検出器。pHの変動や酸化還元電位の変動を用いて測定を行う。
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。
The pump is in command of delivering the cellular phase at a constant stream charge. This makes certain that the mobile period is continually fed on the column.
Gas samples are gathered by bubbling them by way of a trap which contains an appropriate solvent. Organic isocyanates in industrial atmospheres are gathered by bubbling the air by a solution of one-(2-methoxyphenyl)piperazine in toluene. The response involving the isocyanates and 1-(2-methoxyphenyl)piperazine both stabilizes them towards degradation ahead of the HPLC Assessment and converts them to some chemical kind which can here be monitored by UV absorption.
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。
one–one μg of injected analyte. Yet another limitation of a refractive index detector is the fact it can not be used for a gradient elution Until the mobile stage parts have similar refractive indexes.
원하는 분석 결과를 얻기 위해서는 컬럼도 충분히 고려하고 선택하는 것이 좋습니다.
Incorrect cell phase composition: The mobile read more stage is responsible for separating analytes. An unsuitable mobile stage composition might cause analytes to elute much too quickly or little by little, leading to broader peaks.
In this section we consider the standard plumbing required to move the cell stage throughout the column and also to inject the sample into your mobile period.

In liquid–liquid chromatography the stationary period is actually a liquid movie coated on the packing material, ordinarily 3–ten μm porous silica particles. Because the stationary period could be partly soluble while in the cell stage, it could elute, or bleed in the column eventually.
