Abstract

The Danish NIR transmission network is used for the determination of protein, moisture and starch in barley and wheat; moisture in rye; oil in rapeseed; and Zeleny in wheat. The network is described briefly. To achieve optimal performance of the field instruments, a standardisation using grain and rapeseed samples has to be conducted at least once a year. The systematic instrument-to-instrument variation is thus virtually eliminated just after standardisation. The random variation between the field instruments and the sub-master is small and not influenced by the standardisation.
