Utilizing Mobile Phase pH to Maximize Preparative Purification Efficacy

Preparative chromatography is a specialized subset of chromatography, where the goal is to purify a target analyte (or analytes in some cases) from a complex mixture of crude sample.  The Continue Reading

What the HILIC is HILIC?

Hydrophilic interaction liquid chromatography (HILIC) is a chromatographic mode used mainly for the separation of polar compounds that are too hydrophilic to be retained in a reversed phase column.

Technical Tip: Bulk HPLC Sorbent Storage and Cleaning for Reuse

In the spirit of frugality, process chromatographers often want to save and store their media for future use. There are steps one can take to store bulk resins for short term and long term use, though it’s worth noting that the media will not last forever.
