Abstract：
:An automated system has been developed and validated for the analysis of liquid formulations (solution and suspension). The system comprises a multi-place magnetic stirrer, a diluter and a diode array UV spectrophotometer. The system can handle a wide range of drug formulation concentrations (> 200 mg ml-1) and gives excellent precision and accuracy with no detectable carryover. The analysis acceptance parameters are user-definable and the analysis process, including interpretation and reporting of the data, is fully automated.
