The amount of trace elements in the human body will have a significant impact on human health. The current research has proved that the lack or excess of some elements is directly related to many diseases. At the same time, trace elements in the human body is a dynamic balance process. The excellent trace element detection technology in the field of geological detection is transplanted to the medical field, and it is ET-70 used with the automatic sampling system to realize the automatic processing flow from the sample tube to the report card, so that it can accurately, quickly and conveniently detect human trace elements. This is of great significance to both health management and clinical diagnosis and treatment of diseases. At the same time, the complex and cumbersome software operating system of scientific instruments is simplified to a visual standard inspection software operating system, which greatly saves training time and computer operation time, and makes the inspection more convenient and fast. It fills the market vacancy of trace element analyzer in China, and is a medical version instrument designed for clinical application in a real sense.
