Size Exclusion Chromatographic columns independent molecules dependent on their size, not molecular body weight. A typical packing content for these columns is molecular sieves. Zeolites are a typical molecular sieve that is definitely employed. The molecular sieves have pores that modest molecules can go into, but huge molecules can not.

Rinse the column by pumping liquid Along with the pump. Nonetheless, only when alkali metals are analyzed working with IC-C1, rinsing is often done by frequently injecting rinse Resolution from your injector even though pumping eluent.

At uHPLCs, we’re committed to providing you with the newest developments in liquid chromatography know-how to meet your analytical and exploration requirements.
