Abstract
In analysis of a sample of unground grain, infrared light is directed towards the sample and is detected after reflection on the sample. For analysis of wheat, light wavelengths within the interval 1050-1400 nm are used with a light detector of PbS-type. A suitable infrared analyzer has a rotatable filter device (5) with a plurality of filters (4) within the stated wavelength interval and is disposed to be able to carry out in a short time period a large number of measurements.
