System Suitability The system suitability test was applied to a representative chromatogram to check the various parameters such as column efficiency, resolution, precision and peak tailing. System Suitability Calculations . The system suitability parameters were evaluated and found to be within the limits. Related chapters have been updated by USP and EP and they also answer the question as to how much a method can be … Suitability Test. Validation procedure. robustness parameters). 1 Dr.C.S.N Institute of Pharmacy, Bhimavaram, Andhra Pradesh, India. Complete formula for calculation (if applicable) and interpretation of results 9 Image of SDS PAGE/ IEF/ electropherogram/ TLC/ UV spectrum/ IR spectrum/HPLC chromatogram etc for blank, sample, standard and system suitability solution . Minor adjustments may be required in order for a system to pass system suitability requirements. All of the results are presented in (Table 1) and (Fig. MattM. 30. The results of validation parameters and System suitability parameters are discussed as follows. the slope of the calibration plot. Table 1: System suitability parameters Parameters Lumefantrine Artemether Tailing factors 3.6 1.1 Resolution 7.218 13.887 Theoretical plates 1992 17863 Relative standard deviation 0.10 1.08 Solubility The solubility of Artemether in mg/ml in all medias can be calculated by the following formula: This allows a comparison of the peak shape, peak width, baseline resolution. procedure was followed as mentioned above. SST is an integral procedure to be done in every drug product analysis (qualitative or quantitative). Parameters to be calculated to provide a system suitability test report.

Procedure: Set the flow rate at an appropriate level and measure the time needed to fill the volumetric flask up Values should normally between 1.0-1.5 and values greater than 2 are unacceptable. System suitability tests are an integral part of gas and liquid chromatographic methods. The asymmetry factor and tailing factor are roughly same and rarely accurate and equal in most cases. The below mentioned parameters are required to be complies during validation of HPLC method for Assay test. This procedure is applicable for analysis to be carried out by High Performance Liquid Chromatography in Quality Control Laboratory. However, allowable adjustments are only those that have been documented in the test method validation (i.e. OBJECTIVE To lay down the procedure for operation of HPLC (Waters Alliance 2695 Separation Module) SCOPE To ensure that the instrument performs satisfactory and gives accurate and reproducible data. Method Development and Validation Parameters of HPLC- A Mini Review. This review describes general approach towards validation process and validation parameters to be considered during validation of a HPLC method. HPLC Basics – Principles and parameters. Five replicates of a standard solution were injected to check the system suitability. The retention time, resolution, theoretical plates, and tailing factor were evaluated for the system. The peak symmetries were <1.5 and these values are according to the United States Pharmacopeia. Execution : Chemist – QC department. Hence the regulatory organizations like USP and EP have recommended this as one of the system suitability parameter. Mini Review. System suitability testing (SST) is required by USP, FDA and EP to check and ensure on-going performance of an analytical systems and methods. They are used to verify that the detection sensitivity, USP29 (Official June 1, 2006) resolution, and reproducibility of the chromatographic system are adequate for the analysis to be done. Yes, I agree with you, system suitability is to be assessed prior to analyzing samples, and I'd go on to say further that the bracketing standards in the analysis queue are important to have, but are not a substitute for the initial five injections of the working standard. System Suitability In addition, prior to the start of laboratory studies to demonstrate method validity, some type of system suitability must be done to demonstrate that the analytical system is performing properly. To lay down a procedure for analysis to be carried out by HPLC and its documentation.
