Lets simultaneous and ongoing operation of up to a few chromatography separations. These could be part of a batch and/or multi-column system
No diffusion, no pores and no void volume make transport amongst cellular and stationary period really rapid
An increase in counter ion (with regard for the practical teams in resins) concentration reduces the retention time, as it makes a robust Levels of competition Along with the solute ions. A decrease in pH cuts down the retention time in cation Trade whilst a rise in pH lessens the retention time in anion exchange.
A small volume of sample to get analyzed is launched for the cellular stage stream which is retarded by distinct chemical or Actual physical interactions Using the stationary period.
This experiment was the beginning from the HPLC growth journey, even though it took One more thirty a long time just before applying pumps to drive a liquid stage with the packed column.
Inverse gradient separations are applied solely when employing a charged aerosol detector and find use inside the pharma industry, in which quantifying impurities in get more info prescription drugs is crucial.
Twin LC strategies are beneficial for any condition when you'll want to raise your sample throughput, like analyzing a sample for residual pesticides and phenolic content material in a single run or performing replicate analyses concurrently.
I would love to join newsletters from Sartorius (Sartorius AG and its affiliated businesses) primarily based of my personalized pursuits.
Stationary stage chemistry dictates the affinity of your sample factors to stick or keep to the column given that the cellular stage moves the sample in the column. Due to this fact, the sample parts traverse the column and elute at distinct prices.
The information of our Web-site is often obtainable in English and partly in other languages. Opt for your preferred language and We are going to explain to you here the material in that language, if accessible.
Pumps change in pressure potential, but their efficiency is calculated on their ability to yield a regular and reproducible volumetric move rate.
Related or semi-connected downstream processing provides substantial enhancements to productiveness, cost, timelines, and facility footprint. Our flexible portfolio lets you select an intensification approach that aligns with the distinctive method aims.
CIM® monoliths are available in several different chemistries and sizes ranging from screening to industrial processing for better yields and enhanced speed.
