    Interlaboratory Studies and Certified Reference Materials for Environmental Analysis: The BCR Approach Book 22 The participation in interlaboratory studies and the use of Certified Reference Materials (CRMs) are widely recognised tools for the verification of the accuracy of analytical measurements and they form an integral part of quality. method performance (collaborative) studies [1], proficiency testing [2], and internal quality control [3]. In some sectors, most notably in the analysis of food, the requirement for methods that have been “fully validated” is prescribed by legislation [5,6]. “Full” validation for an analytical method is usually.

      Youden two-sample diagram, two-sample collaborative testing, two-sample plan, Youden plot or Youden analysis is particularly aimed at interlaboratory comparisons [19, 20]. The raw results provided by the participating laboratories are treated by a statistical method applied by the organizing centre of the trial. The analysis for lead of whole crowns from deciduous incisors has been used as an index of the cumulative exposure to lead of children during the prenatal period and until the time of shedding the.

ISBN  Inter-laboratory studies are performed with different aims and consequently require different evaluation methods and statistical treatment. The review considers method-performance studies (collaborative trials), laboratory-performance studies (proficiency tests), collaborative bias evaluation, inter-laboratory evaluation of to-be standard methods as well as certification studies for reference Cited by: The minimum requirements accepted by consensus of 27 participants at an IUPAC Workshop for the design, conduct, and interpretation of collaborative interlaboratory studies are given.

Internationally accepted protocols have been established for the “full” validation of a method of analysis by a collaborative. It is important that collaborative (interlaboratory) studies be analyzed carefully. for collaborative studies of chemical analytical methods.

Our objective is to describe procedures to validate analytical mcdi-ods used for estimating concentrations of a specific analyte in a given material with a minimum of uncertainty.
