Thamma Narendra Kumar et al., IJSID, 2011, 1 (3), 395-421Figure-12: Cyanoguanidine impurity solution ChromatogramSystem suitabilityFigure-13: Melamine impurity solution ChromatogramSystem suitability parameters were established by injecting the freshly prepared standard solution (sixreplicate injections) in to the chromatographic system. Calculated the percentage relative standard deviation forpeak area and results found to be satisfactory. System suitability chromatograms represented in figure-2, 3 andtabulated the results in table-1.Table–1: System Suitability ResultsStandard inj N°Metformin Peak area1 39757302 39832213 39823684 39839415 39865266 3968755Mean 3980090%RSD 0.2Theoretical Plate count 4518Tailing Factor 1.2International Journal of Science Innovations and Discoveries Vol 1, Issue 3, November-December 2011403
