Anirbandeep Bose* Acharya and BM Reddy College of Pharmacy, India *Corresponding author: Anirbandeep Bose, Acharya and Bm Reddy college of Pharmacy, India, Tel: 91- The RSD for the peak areas from six replicate injections was calculated. RESULTS AND DISCUSSION A Reverse phase HPLC method was developed keeping in mind the system suitability parameters i.e. USP <1225> System suitability tests are based on the concept that the equipment, electronics, analytical operations, and samples to be analyzed constitute an integral system that can be evaluated as such. System suitability test: Before performing any validation experiments, you should establish that the HPLC system and procedure are capable of providing data of acceptable quality. System suitability parameters Depending on the theoretical plate count, and other parameters as pressure etc system suitabil-ity parameters were studied. The asymmetry factor and tailing factor are roughly same and rarely accurate and equal in most cases. The peak symmetries were <1.5 and these values are according to the United States Pharmacopeia. MattM. 1.0 Specificity : Demonstrate the separation of the analyte from Placebo. Linearity The linearity of the method was demonstrated over the concentration range of 10-50 µg/ml for DAS and 5-25 µg/ml for PDH. Liquid chromatography is a well-established technique for the separation of substances. Conduct the following forced degradation studies to obtain degraded sample, preferably 10 – 50% degradation and demonstrate the separation of the analyte from degradants. The below mentioned parameters are required to be complies during validation of HPLC method for Assay test. Calculation of Peak Asymmetry 5. PROCEDURE .
