APPLICATION NOTE 41/2021

Herzog recently introduced a novel technology enabling the production of granular chips especially suited for thermal evolution analysis. In this application note we investigated whether the automatic collection and transport of granular chips may cause contamination from chips that have become stuck throughout the pneumatic tube line. For this purpose, we examined the impact of inserting a sample with high C and S content on the analytical outcome in a series of samples with low C and S content. In ten milling cycles with a total of 80 trials, we found no evidence of significant contamination (student’s t-test, P<0.05). The reverse case, insertion of a low-concentration sample into a sample series with a high C and S content, also did not reveal any contamination. This shows that the fully-automatic process of chip production, collection and transport results in reliable analytical results.
