Abstract
A method and apparatus for determining at least one component of a sample of a particulate material, such as grain or seed, on the basis of a permittivity value of the sample. Before measuring the permittivity value the sample is compacted to a predetermined degree, preferably by vibrating the sample. Preferably, the sample is vibrated while being introduced into a sample container or receptacle in which the sample is exposed to an alternating electric field for determining said permittivity value.
