The development and validation of methods of analysis for quality control
For new products, it is essential to develop suitable analysis methods for release or for stability testing. As a ISO-accredited and DCA-approved contract laboratory in India, we can draw on an enormous wealth of knowledge and can contribute to your achieving the desired results quickly with targeted literature research and feasibility studies.
The validation of analytical methods is demanded in the GMP regulations. The methods of analysis for a product must be validated at the latest before the start of clinical trials. Fully comprehensive validation in accordance with the ICH and FDA guidelines up until approval is absolutely necessary. Validation of an analytical method provides evidence that the selected method is both suitable and applicable for the analysis purposes intended.
The scope of the validation will be determined together with you in a validation protocol. The experimental work will be carried out by qualified and trained personnel and the results will be summarised in a comprehensive validation report.
Do you require support in method development, or would you like to know whether product-specific validation is necessary?
Distinctions are made between the following different types of analysis:- Identification testing
- Quantitative determination of the level of impurities
- Limit tests for the monitoring of impurities
- Quantitative determination of the active substance content
The identity of an analyte is confirmed by means of an identification. This is generally performed by comparing a sample with a reference standard using chromatographic or spectroscopic methods. The test for contamination can be performed either by using a limit test or by quantitative determinations. Different validation parameters are required according to the type of the test. Content determinations enable the quantitative determination of the analyte in a sample. Chromatographic methods are mainly used and validated in content determinations. Additional methods for release reactions of the active ingredient in combination with HPLC and UV are validated for the finished product.
Procedure for validations
The procedure parameters to be determined are dependent on the type of analysis and are described in the ICH guideline Q2(R1). The “Validation of Analytical Methods” table gives an overview of this.
