Tamilnadu. E-Mail: velmpharm24@gmail.com A precise‚ accurate and rapid RP-HPLC method has been developed and validated for the simultaneous estimation of Tamsulosin Hydrochloride and Finasteride in tablet dosage form. Chromatography was carried on RP – 18e Hiber RT (250 × 4.6) column using Water:Methanol (30:70%) v/v as mobile phase at a flow rate 0.7 ml/min and the effluent was monitored at 225 nm. The retention times of Tamsulosin Hydrochloride and Finasteride were 5.4

of diet Coke® using HPLC as investigation tool. Introduction High Performance Liquid Chromatography (HPLC) is one of the most widely used analytical techniques of nonvolatile organic compounds. Chromatographic processes can be described generally as mass-transfer between stationary and mobile phase. In HPLC‚ a liquid mobile phase is used to separate individual components of complex mixtures. Stationary phase can be either liquid or solid (like that in experiment). The standard design of HPLC
