Discussion on Round-Robin Testing in Size Exclusion Chromatography Using Polyamides as an Example

Abstract

The results of the validation of a high-temperature steric exclusion chromatography (HTSEC) method using benzyl alcohol for the characterization of polyamides 6, 11 and 12 are given. The validation consists of the statistical evaluation of the method in term of repeatability and of intralaboratory reproducibility from a collection of data on one commercial PA11. The need of a further step for validation of this method is discussed to examine different technical aspects and, to validate the method through round-robin testing.
