Background
In the chemical analysis process of smelting samples, the samples are completely dissolved by using triacid and hydrogen fluoride, diluted and transferred to a volumetric flask for constant volume, and then an atomic absorption instrument is used for measuring the tastes of elements such as nickel, copper, iron, cobalt and the like of the sample solutions. In the process of measuring the sample by the atomic absorption instrument, the valuable metals such as nickel, copper, iron, cobalt and the like in the solution in the volumetric flask often exceed the standard range of the atomic absorption instrument, so that the solution needs to be diluted to a proper multiple, and the specific taste of the sample solution can be detected and analyzed by the atomic absorption instrument after the taste range of the detected solution is within the standard range of the atomic absorption instrument. When the solution is diluted, the pipette bulb and the pipette bulb are usually used for manually taking the solution for dilution, and the pipette bulb needs to be washed with the original solution three times when being used for diluting the next sample once again, so that a great deal of manpower and time are wasted in the sample dilution process, and the atomic absorption instrument is in a state of waiting for the sample solution, which is very inconvenient. Therefore, the liquid taking device in the sample dilution liquid taking dilution process needs to be improved.
