The objective of a formal method transfer is to ensure that the receiving laboratory is well trained, qualified to run the method in question, and gets the same results witing experimental error as the iniating laboratory. The development and validation of robust methods and strict adherence to well documented standart operating procedures is the best way to ensure the ultimate sucess of the methode. This installment of ''Validation Viewponit'' examines the analytical method transfer process, including protocol, documentation, and some possible chromatographic pitfalls to avoid.

A synopsis of the authors' work detailing the use of chemometric response surface methodology (RSM) in two capillary electrophoresis (CE) studies is described. They demonstrate the usefulness of employing RSM to specific CE applications, thereby proving the utility of chemometrics design in experimental optimization.

Over the course of a drug product's life (as much as 15-20 years or more) many significant advances in technology will occur. Implementing new analytical techniques (for example, capillary electrophoresis), or advances in existing technology (for example, sub-2-μm liquid chromatography [LC]) can significantly impact business practices (return on investment) and product quality. However, in a regulated laboratory, implementing new technology can present many challenges.
