Abstract

  A simple Gas Chromatography-Head Space(GC-HS) method for the determination of residual solvents in simvastatin tablets using Nitrogen as the carrier gas at 1.3 mL/min with DB-624 (30 m X 0.32 mm ID X 1.8 μm) as column using Flame Ionisation Detector(FID) as detector was developed. The developed method was validated and parameters were to be found within the limits of international conference on harmonization (ICH) guidelines. The retention time for residual solvents individually and in spiked standard solution was determined. The % RSD for six injections should be NMT15%. The percentage recovery ranges from 80 - 120%. The correlation coefficient R² ≥ 0.99. The limit of detection and limit of quantification was found to be specific. Precision, method precision and intermediate precision was found to be within the acceptance limit. Finally the sample was tested for the presence of residual solvents mainly Isopropyl alcohol was found.
