FIELD: measurement equipment.SUBSTANCE: method involves sampling of a test sample of cleaned crystals of natural diamonds and determination of impurities and impurities. The test sample of cleaned crystals of natural diamonds is subject again to a full cleaning cycle. Before and after repeated cleaning, recording of absorption spectra of diamond crystals of the test sample and determination of numerical value of colourful coordinates of diamond crystals and content in the test sample of diamond crystals with a different type of impurities before and after repeated cleaning is performed. Quality of the primary cleaning is estimated as per the significance of differences between design factors, which is estimated as per Student t-criterion.EFFECT: improving efficiency and accuracy of quality control of the used cleaning process of diamond crystals.2 cl, 1 tbl |
