Assembly, for analysis of mineral samples, has rotating sample distributor in vacuum chamber, moved by rotary manipulator, to advance selected sample into isolated recess for transfer to crucible

摘要

The system for the analysis of mineral samples has a chamber under vacuum, containing at least one sample distributor, with radial recesses (8) on its upper surface (9) to hold the samples. The distributor has a supporting base (6) to carry at least one rotating sample carrier (7), shifted by a rotary manipulator (12). The movements are controlled to push a selected sample into a central recess (20) in the shape of a funnel by a shaft (19) triggered by an actuator, to be isolated by a valve and carried into the rest of the system.
