The invention discloses a sample preparation device for noble metal analysis. The device comprises an ampoule, wherein a heat conducting plate is arranged at the bottom of the ampoule; the inner wallof the ampoule is provided with a heat insulation plate and an ampoule anti-corrosion glass layer, and the ampoule anti-corrosion glass layer is positioned on the inner side of the heat insulation plate; a sample preparation reaction chamber is arranged in the ampoule; an ampoule bottle neck is arranged above the sample preparation reaction chamber; the top of the ampoule bottle neck is provided with a bottle mouth; the inner side of the bottle mouth is provided with a ground opening; the top of the bottle mouth is provided with two detachable cold trap pressing plates; and the top of each detachable cold trap pressing plate is provided with a detachable handle, a detachable cold trap is arranged between the detachable cold trap pressing plates, and the detachable cold trap penetrates through the inner portion of the ampoule bottle neck. Through a liquid sealing funnel, a bent pipe and the detachable cold trap which are arranged, the leakage of a volatilized metal salt is reduced, andtherefore the purpose of reducing the volatilization loss of the metal salt when the device works is achieved.
Description
technical field [0001] The invention belongs to the technical field of metal sample preparation tools, and is specifically used for a sample preparation tool for precious metal component analysis, in particular a sample preparation device for precious metal analysis. Background technique [0002] With the rapid development of China's economy, the opening of the gold market and the soaring price of gold, various jewelry trading markets using gold as raw materials have become increasingly active. As jewelry with precious metal gold as the main raw material, its value also mainly depends on the quality and purity of gold. [0003] Precious metals are insoluble metals, and aqua regia is generally used to dissolve samples in their analysis and detection, accompanied by heating, and requires a long time to react. At the same time, precious metals are expensive and have high requirements for the accuracy of sample analysis values. The usual sample preparation and dissolution equi...
