Abstract

An apparatus for the preparation of a sample for X-ray spectrometry comprises a crucible for fusible material, a vessel covering the crucible in a first position and serving to receive cast material from the crucible in a second position, an induction coil wherein the crucible is disposed for simultaneously heating the crucible until the material therein is fused and preheating the vessel covering the crucible, a mobile support mounted for rotation about a horizontal axis extending perpendicularly to the axis of the induction coil, the induction coil being affixed to the support and rotation of the support being capable of agitating the crucible during fusion of the material and for turning the crucible from an upright position wherein the material is fused to a casting position wherein the fused material is cast from the crucible, a casting table below the induction coil, and a sliding ramp connecting the casting table to the mobile support for slidingly guiding the vessel from the first to the second position below the crucible when the crucible is turned into the casting position.
