I want to enroll in newsletters from Sartorius (Sartorius AG and its affiliated providers) dependent of my particular pursuits.

최상의 결과를 위해서는 올바른 시약을 사용함으로써 피크 대칭성을 개선할 수 있습니다.

, which permits us to discover a broad array of cellular phases with only 7 experiments. We start by altering the amount of acetonitrile within the mobile phase to produce the absolute best separation inside the desired Investigation time.

Try to remember, consulting your instrument guide and also the manufacturer's technological guidance can be precious resources when troubleshooting certain issues with the HPLC system.

A reversed-phase HPLC separation is performed utilizing a cell stage of 60% v/v water and forty% v/v methanol. What is the cellular stage’s polarity index?

カラム周辺の温度の変動によって溶出時間が安定せず再現性が悪くなる場合があるため、カラム温度を一定に保つために使用する。またカラム温度を分離条件のパラメーターの一つとして積極的に利用する場合もある。

The solvent reservoir retail outlet the solvent or cell period to supply on the column as necessary. The solvent is pumped into the column in a selected movement rate.

, for instance, has two mobile period reservoirs which have been useful for an isocratic elution or perhaps a gradient elution by drawing solvents from just one or both equally reservoirs.

Immediately after loading the sample, the injector is turned into the inject situation, read more which redirects the mobile phase with the sample loop and onto the column.

충전제는 실리카겔 혹은 중합체의 미세입자로 표면에 화학 수식이 되어 있는 경우가 대부분이며 여러 종류가 있습니다.

이 두 용매는 혼합되지 않기 때문에 분액깔대기에 각각 동량을 넣어 혼합하려고 해도 바로 물층과 기름충, 이렇게 두 개의 상으로 분리됩니다. 여기에 다른 성분이 첨가되어 혼합되면 분석물질은 어느 쪽 상에 존재할까요?

A lot of different types of detectors have already been use to observe HPLC separations, the majority of which utilize the spectroscopic procedures from Chapter 10 here or the electrochemical tactics from Chapter eleven.

Analyte solubility: The preferred solvent should effectively dissolve the focus on analytes. Experiment with different solvents to discover the best just one for the precise sample.
