Department of Chemistry hop

The laboratory is equipped with top instrumentation for gas and liquid chromatography, UV-VIS spectroscopy and conductometry.

Department activities are focused on:

  

Analyses of hops and hop products for growers and business organizations in order, declaration of Quality for the purpose of buying and selling hops.

  

Research projects financially supported by the State (GAČR, NAZV, MPO, MŠMT) in the field of breeding, growing and processing hops, content and composition of secondary metabolites of hops and the occurrence of contaminants.
