Heavy metal detection device for cosmetics

Abstract

The invention discloses a heavy metal detection device for cosmetics, and relates to the technical field of cosmetic detection. The heavy metal detection device comprises a shell, a detection box is fixedly inserted into the side wall of the shell, a detection box is arranged in the detection box, two symmetrically-arranged feeding pipes are arranged on the side wall of the detection box, first electromagnetic valves are arranged on the side walls of the feeding pipes, a filter plate and a heating plate are arranged in the detection box, and the filter plate is positioned above the detection box. The detection box can be vacuumized before reaction, the influence of air on a detection result is avoided, the detection result is more accurate, meanwhile, carrier gas can be automatically filled into the detection box after the detection box is vacuumized, the gas filling process of the carrier gas is more convenient, more energy-saving and more environment-friendly. The mercury atoms and the carrier gas can be fully stirred and mixed before being introduced into a mercury analyzer for detection, so that the detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of cosmetic detection, in particular to a heavy metal detection device for cosmetics. Background technique [0002] Cosmetics are daily necessities, and now many unscrupulous businesses will use impure raw materials or add heavy metals in the cosmetics production process in order to make huge profits. Mercury is also a common additive. If the content of this heavy metal is not controlled at a certain level If it is used on human skin, it may cause various diseases. To see whether the cosmetics are qualified to be used, it is necessary to detect heavy metals. [0003] When the mercury content is detected, potassium borohydride is added to the cosmetic sample for reaction. Mercury ions in the cosmetic react with potassium borohydride to generate atomic mercury, and after high temperature heating, mercury vapor is formed and brought in by the carrier gas (argon gas) The detection is carried out in a mercury de...

Problems solved by technology

[0004] However, this detection method is not in a vacuum environment during the detection, and the air will affect the accuracy of the detection results. At the same time, it is not convenient and fast to feed the carrier gas, and mercury vapor is brought into the mercury detector by the carrier gas. Before the detection in the medium, it was not fully mixed, thus affecting the accuracy of the detection results
