Pharmaceutical Technology Europe. This article presents a simple and systematic approach to HPLC method development, beginning with sample preparation and finishing with practical analytical method validation. The wide variety of equipment, columns, eluent and operational parameters involved makes high performance liquid chromatography HPLC method development seem complex. The process is influenced by the nature of the analytes and generally follows the following steps:. Depending on the overall requirements and nature of the sample and analytes, some of these steps will not be necessary during HPLC analysis.
A rapid, simple, and sensitive RP-HPLC analytical method was developed for the simultaneous determination of triclabendazole and ivermectin in combination using a C18 RP column. The mobile phase was acetonitrilemethanolwateracetic acid 56 36 7. A nm UV detection wavelength was used. Complete validation, including linearity, accuracy, recovery, LOD, LOQ, precision, robustness, stability, and peak purity, was performed. The calibration curve was linear over the range The intraday precision obtained was
Objective: The present work was undertaken with an aim to develop and validate a rapid reverse-phase high-performance liquid chromatography RP-HPLC method for the estimation of curcumin and cyclosporine in the capsule dosage form. Separation of drugs was achieved in an isocratic mode and elution was monitored using PDA detector at nm. Results: Retention time of the curcumin and cyclosporine were found to be 3. Conclusion: The proposed method was found accurate, precise and specific for the determination of curcumin and cyclosporine in bulk as well as in capsule dosage form. Thus, the present method can be used for routine analysis and quality control of curcumin and cyclosporine in bulk and capsule dosage form. Peer Review. Plagiarism Check.
Thomas A. Little, PhD, is president, Thomas A. Design of experiment is a powerful development tool for method characterization and method validation. Design of experiments DOE is a well-proven characterization approach within product and process development and a key aspect of quality by design. Recently, more attention has been placed on applying DOE to analytical methods. DOE for analytical methods has three major applications: method development for new methods or those that need improvement, method validation, and quantitation of the influence of analytical methods on product and process acceptance and out-of-specification OOS rates.
PDF | High performance liquid chromatography (HPLC) is an essential analytical tool in assessing drug product. HPLC methods should be able.
A new selective and sensitive high-performance liquid chromatography HPLC method was developed for the quantification of diclofenac sodium DS in pharmaceutical dosage form using lidocaine as internal standard IS. Chromatographic separation was achieved on a symmetry C18 column 4. The method was validated to fulfill International Conference on Harmonisation ICH requirements and this validation included specificity, linearity, limit of detection LOD , limit of quantification LOQ , accuracy, precision and robustness. All results were acceptable and this confirmed that the method is suitable for its intended use in routine quality control and assay of drugs.
