Analysis of error cases induced with regard to the calculation of the dilution factor during the proficiency test of certified odor measurement agencies

Abstract: The aim of this study is to analyze error cases induced during the proficiency test of certified odor measurement agencies. In the case of the homogeneity test performed in three panel groups, the geometric mean dilution factor of the site boundary PTMs(proficiency testing materials) was 1.4 ± 0.2, 1.7 ± 0.2, 1.8 ± 0.1 and that of the outlet PTMs was 3.7 ± 0.2, 3.7 ± 0.3, 3.7 ± 0.3, respectively. In the case of the stability test for 72 h, the geometric mean dilution factor of the site boundary PTMs was 1.6 ± … Show more

“…The value was 3.690 ± 0.033 for the outlet PTMs. The deviation between the hourly log values of dilution rates was not significant, which indicates that the stability of the PTM samples was maintained over time [17].…”
