The microbiological bioassay, the UV-spectrophotometry and the high performance liquid chromatography (HPLC) methods for assaying sparfloxacin in tablets were compared. The accuracy, repeatability, and precision of each ...

A first derivative spectrophotometric method has been developed for the determination of parathion and p-nitrophenol in vegetable tissues. Ethanol was used as solvent for extracting the compounds from the tissues and ...

Objective. The purpose of this study was to evaluate the release of formaldehyde by some root canal filling materials. Study design. Two older endodontic sealers, AH 26 and Endomethasone, and 2 recently available sealers, ...
