Agilent Exploiting RRHT Columns with Different C18 Selectivities to Quickly Develop Methods for Endocannabinoids

About this manual

Agilent Technologies presents an application demonstrating how Robust HPLC methods are developed by manipulating selectivity, efficiency, and retention. The document focuses on the use of ZORBAX RRHT columns to significantly reduce method development time for selected endocannabinoids compared to standard analytical columns.

The study examines four specific endocannabinoid fatty amides: Arachidonoylethanolamide (AEA), 2-arachinoylglycerol (2-AG), Palmitoylethanolamide (PEA), and Oleoylethanolamide (OEA). By utilizing various ZORBAX RRHT columns with different bonded phases and lengths, the authors illustrate how to quickly optimize separation resolution using volatile mobile phases compatible with mass spectrometry.
