This Technical Report covers the results from two ring tests (A and B, see Introduction) to compare the repeatability and reproducibility of the standardized method for the determination of EDDHA and EDDHMA by ion chromatography (EN 13368 2:2001) with a non-standardized alternative method using ion-pair chromatography ("Lucena-method", given in Annex A). This Technical Report also provides the results of an univariate multifactorial ANOVA test and F-test for ring test A and F-test for ring test B to verify the significance of the reproducibility and the repeatability data.
