Abstract
The invention relates to a device for preparing a sample meant for continuously operated on-line analysis and containing finely divided, pulverous material, so that the sample is suited for an analysing method designed to analysing the surface layer of the sample, and that a sample flow extracted from the material flow by a sampler is conducted to the device. According to the invention, in order to realize an essentially even sample material bed (10) to be transported past the analyser device (11), the height of the sample material in the sample material bed feeder element (5) is maintained essentially at a predetermined value.
