EUROLAB laboratory provides testing and compliance services within the scope of USP 37-NF 32 standard. The purpose of this study was to evaluate the effect of polystyrene divinylbenzene copolymer HPLC columns on the chromatographic performance of the USP digest method for doxycycline hyclate.
The comprehensive method was applied based on the evaluation of the chromatographic performance of six USP-defined L21 polystyrene divinylbenzene HPLC columns. Modifications to the method were based on the USP for chromatography.
The method has been validated for the determination of doxycycline hyclate and its impurities in commercially available drug products. A number of different polystyrene-divinylbenzene columns were tested and failed to provide selectivity for the solubility of doxycycline and its impurities.
