CAC/GL 37 – 2001 Page 1 of 1,HARMONIZED IUPAC GUIDELINES FOR THE USE OF RECOVERY INFORMATION IN,ANALYTICAL MEASUREMENT,CAC/GL 37-2001,The Harmonized IUPAC1 Guidelines for the Use of Recovery Information in Analytical Measurement,were adopted by reference for Codex purposes with the exception of the first two sentences of,Recommendation 12.,For Codex purposes, Recommendation 1 of the IUPAC Guidelines therefore reads as follows:,It is of over-riding importance that all data, when reported, should (a) be clearly identified as to,whether or not a recovery correction has been applied and (b) if a recovery correction has been,applied, the amount of the correction and the method by which it was derived should be included,with the report. This will promote direct comparability of data sets. Correction functions,should be established on the basis of appropriate statistical considerations, documented,archived and available to the client.,Reference,Harmonised Guidelines for the Use of Recovery Information in Analytical Measurement,(Pure Appl. Chem., Vol. 71, pp. 337 – 348, 1999),1 International Union of Pure and Applied Chemistry,2 “Quantitative analytical results should be corrected for recovery unless there are specific reasons for not,doing so. Reasons for not estimating or using correction factors include the situations where (a) the analytical,method is regarded as empirical, (b) a contractual or statutory limit has been established using uncorrected,data, or (c) recoveries are known to be close to unity. However,…..”……
