Discussion on Detection Methods of Trace Element Analyzer

With the continuous improvement of medical standards, the relationship between trace elements and human health has been fully recognized. People are also more concerned about how to supplement trace elements and how to eliminate harmful elements. Trace elements are a balanced process in the human body, and the lack of trace elements and excesses can have adverse effects on the human body. Therefore, how to detect the trace element content of human body accurately, quickly and conveniently becomes a problem that medical workers need to solve. At present, all levels of medical and health care units in China, especially maternal and child health care units, children's hospitals, general hospitals, etc., have already incorporated human elements (lead , Zinc, Copper, Calcium, Magnesium, Iron, etc.) As a regular item. How to choose a suitable instrument is the most important issue faced by the hospital administrator in the procurement process. Among the selections, the first one is to select an accurate and standard measurement instrument, and then the simplicity of the operation procedure and the safety of the equipment should be considered. And stability, but also to consider the examinee's economic affordability and degree of impact and the speed of detection, and finally also take into account the technological advancement and utilization of the instrument, so as to ensure the appropriate benefits.

Here's a brief introduction to the trace element detection method:

Currently available methods for human trace element detection include isotope dilution mass spectrometry, molecular spectroscopy, atomic emission spectrometry, atomic absorption spectrometry, X-ray fluorescence spectrometry, neutron activation analysis, biochemistry, and electrochemical analysis. And so on, but widely used methods in clinical medicine are mainly biochemical methods, electrochemical analysis, and atomic absorption spectrometry.

The characteristics of biochemical methods (zinc protoporphyrin method, dithizone method, other colorimetric methods, etc.): The use of large amounts of blood, processing speed is not fast enough, and the types of detection elements are limited.

Electrochemical analysis, also known as potentiometric stripping or stripping voltammetry: This kind of instrument has a low price, can be used for trace measurement, can measure many elements, but the pollution to the environment is more serious. Nowadays, many institutions use electrochemical analysis instruments. After all, their price advantages are obvious, and they can meet the detection requirements of most hospitals. Electrochemical analysis is a good choice when the environmental requirements are not too high. .

Atomic Absorption Spectrometry, also known as atomic absorption spectrophotometry, has high sensitivity, high accuracy, selective number, less interference, fast speed, easy automation, wide range of measurable elements, simple structure, low cost, etc. However, the instrument is more expensive and is now generally used only in more advanced hospitals.

Now medically, the detection methods of the trace element analyzer mainly include the above methods. The instrument of which detection method is selected requires you to select the appropriate detection method according to your own economic ability and testing requirements.
