✦ Synopsis

Adrenaline was determined in injections containing procaine in a lOOO-fold excess by reversed-phase high-performance liquid chromatography using UV detection at 205 nm and aqueous sulphuric acid (100 pmol/l) as eluent. The relative standard deviation was 2.1%, and the method was selective in the presence of adrenaline degradation products. Changes of the capacity factor with pH and ionic strength of the eluent were studied, and a simple model is suggested to explain the retention data.

## Abstract A stability‐indicating MEKC was developed and validated for the analysis of rupatadine in tablet dosage forms, using nimesulide as internal standard. The MEKC method was performed on a fused‐silica capillary (50 μm id; effective length, 40 cm). The BGE consisted of 15 mM borate buffer a
