Food Analysis Proficiency Assessment Scheme

When information on the stability of analyte in matrix during typical conditions of storage is unavailable from the literature or from proficiency testing (PT) providers, such as the food analysis proficiency assessment scheme (PAPAS), this information shouid be developed in the laboratory as part of the method development and validation. However, a study to obtain information on stability of the analyte first requires the availability of a validated method if results are to be considered reliable. When a method is being developed to introduce a test capability for a new analyte into the laboratory, the new...

Two UK proficiency testing schemes are the Food Analysis Performance Assessment Scheme (PAPAS), which replaced NAMAS in 2000, which is arranged by the Central Science Laboratory, with details at http //ptg.csl.gov.uk/fapas.cfm...
