APPARATUS FOR THE AUTOMATIC PREPARATION OF SAMPLES FOR ANALYSING |
摘要 |
An apparatus for preparing test samples for chemical analytical testing has an electric coil adapted to receive a crucible and connected to a source of electricity. The crucible is formed by an outer vessel of a noble metal and by an inner vessel formed of a rigid refractory material that is a good conductor of heat and that is not wettable by the sample. Normally platinum or a platinum alloy is used for the outer vessel and vitreous carbon is used for the inner vessel. The apparatus further comprises a high-frequency electricity supply for supplying electricity to the coil and thereby heating the crucible and the sample therein, a casting receptacle at a lower station below the upper station and adapted to receive the melted sample, a dissolving receptacle at the lower station, and a bath of a solvent for the sample in the dissolving receptacle. |
