Abstract
This key comparison is one of a series of key comparisons in the gas analysis area assessing core competences (track A key comparisons). Such competences include, among others, the capabilities to prepare primary standard gas mixtures (PSMs) using static gravimetry, perform the necessary purity analysis on the materials used in the gas mixture preparation, the verification of the composition of newly prepared PSMs against existing ones, and the capability of calibrating a gas mixture.
