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。
각각 다른 산업 분야에 대한 자세한 정보 및 다양한 카테고리는 다음 써모 피셔 사이언티픽 학습 센터에서 산업 및 응용 과학 페이지를 확인하세요.
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.
Lowering the level of acetonitrile and increasing the quantity of h2o in the cell will maximize retention instances, delivering more time to result a separation.
. Example of a typical high-performance liquid chromatograph with insets demonstrating the pumps that go the mobile stage in the system plus the plumbing used to inject the sample into your mobile phase.
Bubbling an inert gasoline through the cellular stage releases volatile dissolved gases. This process is called sparging.
The interface between the HPLC as well as mass spectrometer is technically more challenging than that inside of a GC–MS because of the incompatibility of a liquid cell period Using the mass spectrometer’s high vacuum need.
The tension helps make the approach much faster compared to column chromatography. This allows utilizing Significantly smaller particles with the column packing content.
식용유를 꺼내고 싶을 때는 기름층을 꺼내서 같은 조작을 하면 분리가 가능합니다.
we discovered how to adjust the cellular phase’s polarity by Mixing collectively two solvents. A polarity index, having said that, is simply a information, and binary cellular section mixtures with equivalent polarity indices may well not resolve Similarly a pair of solutes. Table 12.5.2
The overarching theory of HPLC is chromatography. It really is a method for separating chemical compounds dependent on their own differential interactions having a stationary phase as well as a cellular phase.
The pressurized liquid is usually a combination of solvents such as h2o, acetonitrile and/or website methanol which is referred to as the cellular section.
ノブをインジェクト側に切り替え、サンプルを流路に注入する。マニュアルインジェクターに電気信号を出力する機能が付いていれば、この時にインジェクション信号を検出器またはインテグレーターに送ることが出来る。
