Summary: The research were found to carry out the original methods todetermine the grade of non-homogenity of the material which willbe used as the referent material.For this reason thepoint-sampling by means of anodic disolution is on the top of theresearch. Influance of various electrolites, the D.C. electrictension and the time of disolution were studied. Also, thespecial mini-electrode was constructed to obtain the data ofelectric tension of the surface of investigated material. Becausethe TLC (Thin Layer Chromatography) gives the best analyticalresults when the point-sampling is applicated, the interactionbetween the chemical substances were studied too. The originalmathematic treatman of the analytic data obtained from thevarious independent laboratories were the object of the research.Also, the simulations, using personal computer, of themetalographic figures of the Pb/Bi inclusions in Al-alloys werethe object of research.

Keywords: non-homogenity, referent material, point-sampling

Research goals: The object of these investigations were to found the original and reliable methods for testing the materials which are designed as the referent material in the analytical instrumental methods.Also the investigations were curried out to found the best methods to make the referent materials and to found the enterpise which are in posssibilities to make it.
