The analytical principle is used to analyze the composition/content of alloy elements and alloy grades. XRF analysis principle is the most advanced alloy analysis principle in the world at present. Compared with traditional chemical analysis methods, XRF analysis can realize real-time analysis, nondestructive testing, without any consumables, and the detection accuracy can reach four decimal places, gradually replacing traditional chemical analysis methods.
The principle of X-ray analysis is to excite the surface of the measured object with X-rays, so that the atoms on the surface have energy level transition, and the detector receives X-rays, and then analyzes the element composition by comparing energy spectra. Each atom has its own specific energy spectrum. German physicist Roentgen (W.C.R? Ntgen) When studying the gas discharge phenomenon in cathode-ray tubes, a sealed glass tube with two metal electrodes (one is called anode and the other is called cathode) is used, tens of thousands of volts of high-voltage electricity is applied at both ends of the electrodes, and the air in the glass tube is pumped out by an air extractor. In order to cover the light during high voltage discharge (an arc lamp), the glass tube is covered with a layer of black cardboard. When he was doing this experiment in a dark room, he happened to find a piece of cardboard soaked in barium platinum cyanide solution emitting bright fluorescence two meters away from the glass tube. Further experiments show that cardboard, wooden boards, clothes and books with a thickness of about 2000 pages can't stop this fluorescence. Even more surprising, when I reached for this fluorescent cardboard with my hand, I saw an image of a hand bone on it.
At that time, Roentgen decided that it was a kind of invisible ray, but it could penetrate the object. Because we can't explain its principle and don't know its nature, we borrowed the unknown "X" in mathematics as the code name, which is called "X-ray" (or X-ray or X-ray for short). This is the discovery of X-ray and the origin of its name. This name has continued to this day. To commemorate this great discovery of Roentgen, later generations named it Roentgen Ray.
At present, the application of this technology in China lags far behind that of foreign companies, especially the Oxford company in Britain is the most advanced in this technology. Our hand-held alloy analyzers X-MET5000 and X-MET5 100 have been well verified in practical application. Mr. Lin Xiang, Oxford China Service Center, 133-3929-2082. Hand-held alloy analyzers X-MET5000 and X-MET5 100 have been widely used in various industries, such as stainless steel detection, metal material analysis, oil pipeline and pressure vessel material detection, scrap metal material detection and recycling, special steel detection, precious metal detection, mineral exploration, ROHS detection and so on. Industries such as thermal power plants are important means to identify material reliability and PMI safety management in high temperature and high pressure industries such as boilers, vessels, pipelines and manufacturing. Metal materials refer to the production processes of iron and steel smelting, nonferrous metals, aerospace, weapons manufacturing, submarines and ships, and other important military and civil engineering industries. In petrochemical refining, petroleum refining, fine chemicals, pharmaceuticals, power plants, aerospace, weapons manufacturing, submarines and ships, the Three Gorges Project and other key military and civil engineering industries, as well as in the process of engineering installation and construction, metal materials are identified to ensure equipment acceptance and material acceptance to meet the requirements of the project. It is a powerful weapon for metal identification and steel identification in the waste metal resource recycling industry.
X-MET5000 alloy analyzer has 3 1 standard elements, such as calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, strontium, zirconium, niobium, molybdenum, rhodium, silver, cadmium, tin, antimony, barium, tantalum and tungsten. The standard components of X-MET5000 alloy analyzer can also be added or replaced.
X-MET5 100 alloy analyzer has 36 standard elements: magnesium, aluminum, silicon, phosphorus, sulfur, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, strontium, zirconium, niobium, molybdenum, rhodium, silver, cadmium, etc. The standard components of X-MET5 100 alloy analyzer can be added or replaced.
Portable XRF light element testing tool is specially designed for metal material reliability appraisal (PMI), scrap metal recycling industry, environmental heavy metal monitoring (soil and RoHS), aviation and automobile industry, ore exploration, field excavation control and mining industry. It can analyze hundreds of alloys, almost covering the alloy brand testing commonly used in the market at present. The alloy series it can detect are as follows:
