Separation: The mobile stage interacts with the stationary section from the column along with the analytes from the sample. This interaction has an effect on how promptly Each individual analyte travels through the column, bringing about their separation.
I'm able to revoke my consent Anytime with effect for the long run by sending an e-mail to unsubscribe@sartorius.com or by clicking within the "unsubscribe" hyperlink in e-mails I've been given.
機械的に高い圧力をかけることによって移動相溶媒を高流速でカラムに通し、これにより分析物が固定相に留まる時間を短くして分離能・検出感度を高くすることを特徴とする。
Throughout the working cylinder’s ahead stoke it fills the equilibrating cylinder and establishes circulation with the column. Once the working cylinder is on its reverse stroke, the flow is preserved through the piston in the equilibrating cylinder. The result is actually a pulse-absolutely free movement.
The data acquisition system data and analyses the detector signals, letting substances to get quantified dependent on their own peak regions from the chromatogram.
이러한 특징으로 고성능 액체 크로마토그래피는 전 세계 모든 과학 분야 및 산업의 기반을 뒷받침하는 과학기술로서의 위치를 확립하고 website 있습니다.
Not For Medical Use
It achieves this by exploiting the differing interactions of sample compounds with two crucial phases: the cell period and the stationary phase. Knowledge the Main parts of the HPLC system as well as their roles is essential for profitable Evaluation.
Lousy resolution indicates analytes elute far too near with each other, making them difficult to tell apart. Here's how you can troubleshoot:
System contamination: Filthy HPLC traces, injectors, or detectors can introduce contaminants that present up as ghost peaks. Flush the system with proper solvents to remove any gathered contaminants.
The HPLC column properties the stationary phase, a critical factor for separating analytes. Selecting the proper column is important:
This certain instrument contains an autosampler. An instrument wherein samples are injected manually will not include things like the attributes demonstrated in the two left-most insets, and has a distinct sort of loop injection valve.
특히 컬럼의 선정은 분석의 get more info 결과에 영향을 미치기에 신중하게 선택하여야 합니다.
, we could position a solvent proportioning valve ahead of a single pump. The solvent proportioning worth connects two or maybe more solvent reservoirs to the pump and decides exactly how much of every solvent is pulled for the duration of Every single of your pump’s cycles. Yet another solution for reducing a pulsed move is to incorporate a pulse damper in between the pump plus the column.
