ABSTRACT:
An automated sample analyzer for induction furnace analysis includes an induction furnace having an induction coil housing with an induction coil therein. The coil housing has a lower opening through which a crucible with a sample can be moved to allow the sample to be analyzed by burning. An elevator is provided for raising and lowering a crucible to and from the induction coil through the lower opening and includes a cover for covering the lower opening. A rotatable and radially movable tray has crucible openings for holding a series of crucibles. The tray openings also radially receive the elevator allowing the tray to move out of the way of the cover as it moves with the elevator while the elevator holds a crucible. A drive is provided for moving the tray rotationally and radially in a series of steps such that the crucible receptacle openings are sequentially moved to and from the elevator for automated loading and unloading of the crucibles on the elevator. A control coordinates the drive elevator and induction furnace. Recording devices automatically record the analysis.
