Sample Processing is powerful tool whenever it is necessary to deduct the volume (weight) of a sample, in order to prepare the analytical sample with suitable for chemical analyses weight, without splitting or losing the representativeness of the initial sample. Our approach, based on “ppm-mineralogy” technology (©NATI Research), allow the customer to obtain the analytical size sample, in where will be not less than 99 vol% of the component of interest, from whole volume of initial sample. Such services are most appropriate for scientific, prospecting, exploration and other applied works, connected with the base and black metals, precious metals (gold, PGEs), rare earth elements and other rare metals and minerals (uranium, diamonds…).
