I would really like to sign up for newsletters from Sartorius (Sartorius AG and its affiliated organizations) centered of my particular passions.
ディテクターから出力された、電気信号を記録し、そこからピークを検出、解釈を行う。結果は、感熱紙等に印字される。装置のコントロールをしないのであれば、どのメーカーの物を使用しても問題はないが、通常は、装置のコントロールも同時に行うため、同じメーカーの物を選択する。
측정 가능한 농도 범위는 컬럼에 의해서도 결정됩니다. 컬럼 충진제의 종류, 입자 지름, 컬럼의 크기에 따라 분리에 최적인 시료 주입량이 크게 다릅니다.
Understanding The essential factors of your HPLC process is critical for maximizing its abilities in a variety of scientific and industrial domains. On account of its capacity to present reputable and actual effects, HPLC is becoming a vital Resource in the fashionable laboratory.
The selection of your column kind is dependent upon the physicochemical Houses of your analytes staying separated.
Peak areas: The area under Each and every peak in the chromatogram is proportional to the level of analyte present, permitting for quantification.
, we could position a solvent proportioning valve ahead of a single pump. The solvent proportioning benefit connects two or even more solvent reservoirs to your pump and determines just how much of each and every solvent is pulled throughout each with the pump’s cycles. A further tactic for getting rid of a pulsed circulation is to incorporate a pulse damper involving the pump as well as the column.
It achieves this by exploiting the differing interactions of sample compounds with two crucial phases: the cell section plus the stationary period. Being familiar with the Main elements of an HPLC system as well as their roles is essential for prosperous Assessment.
). Because the tubing and fittings that have the cellular period have strain boundaries, a higher back strain demands a reduced stream price and an extended Examination time. Monolithic columns, during which the stable aid is just one, porous rod, offer column efficiencies comparable to a packed capillary website column whilst permitting for more quickly move prices. A monolithic column—which ordinarily is similar in size to a traditional packed column, Whilst scaled-down, capillary columns also can be obtained—is prepared by forming the mono- lithic rod inside of a mould and covering it with PTFE tubing or possibly a polymer resin.
Ion-Trade chromatography relies on the separation of substances centered on their own charge. The stationary phase has billed groups that catch the attention of and keep oppositely billed ions from the sample.
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?
The pressurized liquid is usually a combination of solvents which include drinking water, acetonitrile and/or methanol which is referred to as the cellular phase.
The elements of a mixture are divided from one another due to their distinctive degrees of conversation Together with the absorbent particles.
