Abstract

The invention provides an automatic sample dissolving device, comprising a mother solution container, an adsorption rod, a tantalum wire, a liquid discharging valve, a liquid discharging coil and an electrode, wherein the mother solution container is provided with a sample inlet and a dissolved sample outlet; the dissolved sample outlet is located at the bottom of the mother solution container and the adsorption rod stretches into the bottom of the mother solution container; one end, which stretches into the container, of the adsorption rod is suspended; the adsorption rod is a hollow glass tube, the suspended end of the adsorption rod is closed, and the adsorption rod is internally provided with a magnet; the liquid discharging valve is located at the dissolved sample outlet of the mother solution container; the liquid discharging coil is a solenoid switch coil and is used for controlling opening and closing of the liquid discharging valve; the tantalum wire is wound around the suspended end of the adsorption rod and the tantalum wire is connected with the electrode to be electrified. With the adoption of the automatic sample dissolving device, the automatic sample dissolving process is realized, and the time for dissolving a sample only needs five minutes; and steam generated in the process of dissolving the sample is cooled on the wall of the mother solution container to be transformed into liquid and the liquid flows back to the container, thereby reducing the pollution to the air.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis instruments, relates to metal element analysis, and is an automatic sample dissolver. Background technique [0002] For domestic chemical analysis instruments, when analyzing metal elements, the standard sample or sample of the dissolved substance must have an electric furnace of about 1000 watts and a high temperature resistant glass beaker, and then pour several milliliters of hydrochloric acid, nitric acid, sulfuric acid , perchloric acid and other chemical reagents are heated to high temperature one by one to make the material standard sample (sample) dissolve and develop color. It takes about 15 minutes for skilled analysts to complete the sample dissolution work of an element, and they must be very careful when dissolving the sample and taking out the mother solution after dissolving the sample. A little carelessness will cause production accidents. Acidic chemical reagents are ne...
