Considering the increase in the extent of strobilurine use in the protection of barley and hop, it was necessary to introduce monitoring of their residues in raw materials, intermediaries and a final product.

This paper addresses some specifics concerning the use of hydrogen as carrier gas in different techniques of sample introduction on chromatographic column.

This article is focused on the chromatographic parameters such as retention time and selectivity after switching to the use of hydrogen or nitrogen.

Some difficulties with substitution of helium as carrier gas by another gas are discussed in this series of papers. Laboratories may be forced to make this change due to “helium crisis”.
