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 present flowing concerning the working electrode and also the auxiliary electrode serves since the analytical signal. Detection restrictions for amperometric electrochemical detection are from 10 pg–1 ng of injected analyte.
전자를 '고정상', 후자를 '이동상'이라 부르며 크로마토그래피에서는 분석자는 고정상과 이동상의 조합에 의해 분석물의 분리를 제어할 수 있게 됩니다.따라서 분석물, 고정상, 이동상, 세 가지 특성의 이해가 크로마트그래피에서 매우 중요합니다.
- 분석결과는 재현성이 우수하며, 특히 오토샘플러 등을 사용함으로써 보다 높은 재현성을 확보할 수 있어 생산성을 한층 더 향상시킬 수 있습니다.
a values, the pH of your cell period has a different effect on Every solute’s retention time, making it possible for us to locate the the best possible pH for effecting a whole separation from the 4 solutes.
분석물의 피크 면적 값(=검출기의 응답)은 정량화를 위해 사용됩니다. 분석자는 분석을 수행하기 전, 분석물의 표준 용액(기지 농도의 시액)을 몇 가지 측정하고, 시료 농도와 획득한 피크 면적 값에 의해 도표된 검량선을 그립니다.
A pulse damper is actually a chamber full of an easily compressed fluid and a flexible diaphragm. In the piston’s forward stroke the fluid in the heartbeat damper is compressed. If the piston withdraws to refill the pump, tension from the growing fluid in the heartbeat damper maintains the movement charge.
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 data acquisition system records and procedures the alerts with the detector, letting with the development of chromatograms as well as quantification of compounds.
we figured out how to adjust the mobile phase’s polarity by blending jointly two solvents. A polarity index, nevertheless, is just a guide, and binary cell section mixtures with identical polarity check here indices may not solve equally a set of solutes. Desk twelve.five.two

Compounds within the sample partition among the stationary period as well as cellular phase in partition chromatography. Compounds which has a more robust affinity for your stationary period invest extra time interacting with it, resulting in slower elution with the column.
Column choice: The stationary period during the column interacts with analytes. Using the Completely wrong column chemistry may result in lousy resolution. Think about using a unique column by using a stationary section that gives better check here selectivity for your personal analytes.
The injector introduces a specific volume of the sample Alternative to the cellular phase stream. Quite a few injection procedures exist, with loop injection currently being a common procedure.
