Tungsten boat can be used in tungsten boat lead cadmium element analyzer. This instrument is a special atomic absorption spectrometer which uses tungsten boat as atomizer to detect blood lead and blood cadmium. It has the advantages of rapid temperature rise, low power, high sensitivity, high temperature resistance, oxidation resistance, not easy to damage, good accuracy and precision. However, at present, most of the testing institutions choose manual injection, so in order to ensure the accuracy and good precision of the data, there are certain technical requirements for the operators.
Tungsten boat is widely used in vacuum coating industries such as gold plating, evaporator, imaging control mirror, heating container, electron beam spray painting, household appliances (shell), mobile phones, toys, and various decorations, as well as sintering or vacuum annealing ship industries in sintering furnace. In an ideal (vacuum, dry) state, connect wires at both ends of the tungsten boat and electrify it. Place the low melting point metal in the middle of the concave. When its temperature rises below 2000 degrees, the metal will evaporate into gas and be plated on the surface of the workpiece.
Human blood lead detection is the best way to understand human lead pollution, which can accurately reflect the recent lead poisoning degree of the body, and is the main means to determine lead poisoning.
Lead is one of the most common environmental pollutants. It is a heavy metal with the greatest toxicity and strong accumulation. It accumulates in human body for a long time and seriously harms the nervous system, hematopoietic system and digestive system. It does great harm to human body, especially to infant's intelligence and physical development.
