It is generally accepted that terminally sterilized injectable articles or critical devices purporting to be sterile, when processed in the autoclave, attain a 10 –6 microbial survivor probability, i.e., assurance of less than 1 chance in 1 million that viable microorganisms are present in the sterilized article or dosage form. Transfer of Analytical Procedures 1224 , Validation of Compendial Procedures 1225 , and Verification of Compendial Procedures 1226 . Verification consists of assessing selected analytical performance In addition to offering a preview of the proposed general chapter, the General Chapters—Chemical Analysis Expert Committee USP 30-NF 25, General Chapter <1225> Validation of Compendial Methods • “Validation of an analytical method is the process by which it is established, by laboratory studies, that the performance characteristics of the method meet the requirements for the intended analytical applications.” 2 á730ñ Plasma Spectrochemistry / Physical Tests USP 40. USP has introduced a new general chapter <1224> on TAP and the new USP chapter will become official with USP-35. The types of chromatography useful in qualitative and quantitative analysis that are employed in the USP procedures are column, gas, paper, thin-layer, (including high-performance thin-layer chromatography), and pressurized liquid chromatography (commonly called high-pressure or high-performance liquid chromatography). The principles of validation are provided in General Chapter Validation of Compendial Procedures <1225>. used (See General Notices 6.30). Fluorescence spectrophotometry is the measurement of the emission of light from a chemical substance while it is being exposed to UV, visible, or other electromagnetic radiation. Alternative procedures must be validated and equivalent to the compendial procedures for the purposes of the test. USP29–NF24 Page 2593. The intention of the following sections is to provide the user with spe- In general, the light emitted by a fluorescent solution is of maximum intensity at a wavelength longer than that of the exciting radiation, usually by some 20 to 30 nm. procedures. General chapter á1225ñ provides definitions and general guidance on the procedures for analytical validation without indi-cating specific validation criteria for each characteristic. The chapter Validation of Compendial Procedures 1225 provides general information on characteristics that should be considered for various test categories and on the documentation that should accompany analytical procedures submitted for inclusion in USP–NF.

It summarizes the types of transfers that may occur, including the possibility of waiver and outlines the components of a transfer process.
