METHOD AND ARRANGEMENT FOR MEASURING IMPURITIES

摘要

The invention relates to a method and arrangement for automatically measuring impurities in a sample. In the solution, the sample (100) is lifted in such a manner that of the sample (100), at least the part to be measured is suspended freely without support. Cameras (104, 106) film the part to be measured of the sample (100) from a direction other than the vertical direction. An automatic image-processing device (112) measures the impurities in the sample in at least one image formed by at least one camera (104, 106).
