Analysis of Corticosteroids

This simple isocratic Method demonstrates good separation of two similar synthetic Glucocorticoids.  This analysis for corticosteroids may serve well for quantitation in pharmaceutical preparations.  This Method would easily translate to LCMS.


Peak:
1. Prednisone
2. Dexamethasone 

Method Conditions:
Column: Cogent Bidentate C18™, 4µm, 100Å
Catalog No.: 40018-75
