This document describes the method of HPLC analysis of glucocorticoids.
The document details a High-Performance Liquid Chromatography (HPLC) method for separating and analyzing various glucocorticoid steroid hormones, including beclomethasone, hydrocortisone, prednisolone, and betamethasone. The method utilizes a reversed-phase column with UV detection at 254 nm.
| Column | 4x 125 mm Hypersil ODS, 5 um |
|---|---|
| Mobile phase A | water |
| Flow rate | 1.0 ml/min |
| UV detector wavelength | 254 nm |
| Column temperature | 25 °C |
The recommended injection volume for this method is 5 ul.
The autosampler temperature was set to 4°C to avoid decomposition of the samples.
The variable wavelength detector operates at a standard cell setting of 254 nm.
