Satisfactory results for a method can be obtained only with equipment that is performing well.

Special attention should be paid to those equipment characteristics that are critical for the method.

For example, if detection limit is critical for a specific method, the instrument’s specification for baseline noise and, for certain detectors, the response to specified compounds should be verified.

Any chemicals used to determine critical validation parameters, such as reagents and reference standards, should be Any other materials and consumables, for example, chromatographic columns, should be new and be qualified to meet the column’s performance criteria .

This proposed procedure assumes that the instrument has been selected and the method has been developed.

It meets criteria such as ease of use; ability to be automated and to be controlled by computer systems; costs per analysis; sample throughput; turnaround time; and environmental, health and safety requirements.

Successful acceptance of the validation parameters and performance criteria, by all parties involved, requires the cooperative efforts of several departments, including analytical development, QC, regulatory affairs and the individuals requiring the analytical data.

The validity of a specific method should be demonstrated in laboratory experiments using samples or standards that are similar to unknown samples analyzed routinely.Green (11) gave a practical guide for analytical method validation, with a description of a set of minimum requirements for a method.Renger and his colleagues (12) described the validation of a specific analytical procedure for the analysis of theophylline in a tablet using high-performance thin layer chromatography (HPTLC).The validation procedure in this particular article is based on requirements for EU multistate registration.Wegscheider (13) has published procedures for method validation with a special focus on calibration, recovery experiments, method comparison and investigation of ruggedness. (14) have described how analytical methods are validated in a Japanese QC laboratory.

The validity of a specific method should be demonstrated in laboratory experiments using samples or standards that are similar to unknown samples analyzed routinely.

Green (11) gave a practical guide for analytical method validation, with a description of a set of minimum requirements for a method.

Renger and his colleagues (12) described the validation of a specific analytical procedure for the analysis of theophylline in a tablet using high-performance thin layer chromatography (HPTLC).

The validation procedure in this particular article is based on requirements for EU multistate registration.

Wegscheider (13) has published procedures for method validation with a special focus on calibration, recovery experiments, method comparison and investigation of ruggedness. (14) have described how analytical methods are validated in a Japanese QC laboratory.

This ensures that one set of consumables can be used for most experiments and avoids unpleasant surprises during method validation.
