The Standardisation of Infratec 1221 near Infrared Transmission Instruments in the Danish Network Used for the Determination of Protein and Moisture in Grains
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.
