Utilization of UV Spectrum in Identification of Tablets

Requests for tablet identification, one of the drug information services, compose as much as 32% of the total requests made to our drug information office. It is often difficult for hospital pharmacists to identify when no information is labelled on the tablet and on the package. In order to settle the difficulty, the contents of tablets were identified by the UV absorption technique, which proved more reliable than the conventional method. As the spectrophotometry is easy to operate and versatile to apply, the technique is one of the most practically useful methods of the tablet identification.
