Use: It is suitable for qualitative and quantitative analysis and isotope ratio determination of trace and ultra trace metal elements, Metalloid elements, and some non-metallic elements in different types of matrix samples, such as geological and mineral resources, environment, biology, life sciences, food, metal materials, polymer materials, electronic products and chemical products.


Instrument Introduction:

ICP-MS has the characteristics of high sensitivity, low detection limit, wide dynamic range and simultaneous multi-element analysis. It is suitable for the routine and quantitative analysis of more than 70 metals, Metalloid elements and some non-metallic elements as well as the determination of element isotope ratios. The Self-oscillation RF generator (40.68MHz) of this instrument can produce strong plasma. The Plasmalok interface can control the energy distribution range of ions. The two channels of RF can completely eliminate the interface discharge. The ion lens has no strong negative voltage to extract ions. The automatic focusing ion lens technology can automatically optimize the transmission rate of each ion; Simulscan is an ion monitor that can automatically expand the dynamic range in one scan. The detection limit of most metal elements can reach the ppt order of magnitude, while the detection limit of the vast majority of non-metallic elements is lower than the ppb order of magnitude. The combination of ICP-MS and HPLC chromatography can be used to analyze the valence states of elements such as As, Pb, Cd, Hg, Cr, and Se in food, drug, biological, and environmental samples.


As a kind of Atomic emission spectrum analysis technology, ICP began in the 1960s and matured in theory, application and instruments in the 1980s. ICP introduces the sample into the plasma light source, the outermost electron of the element atom or ion to be measured is excited in the Excited state, and the compound light emitted by the energy level transition generated by the Excited state particles returning to the ground state is decomposed into Monochromatic radiation through the Photosystem. Based on the wavelength and intensity of the characteristic spectrum, conduct qualitative and quantitative analysis of the side elements. At present, this instrument is widely used in scientific research units both on and off campus. Avio 200 is the 16th generation ICP-OES product of Platinum Elmer Company. It adopts a vertical torch tube design, greatly improving the resistance to the sample matrix. Both saturated salt water and gasoline can be directly injected; The precision and accuracy of the instrument have also reached the highest level of similar instruments, and the sensitivity of the instrument has also been greatly improved. (1) Full spectrum data collection, easy and fast implementation of full spectrum full reading function; (2) Patented CCD detector, the fastest solid-state detector in the industry and the highest precision it brings; (3) The Spectral resolution of the optimized Photosystem is the best; (4) Tail flame elimination and substrate tolerance; (5) Plasma camera: can monitor the plasma status at any time; (6) High precision MFC control: Accurate control is the basic guarantee of excellent performance; (7) Axial observation/radial observation - high and low concentrations can be detected in the same operation for better quality control and more accurate results; (8) Injection system: AVIO 200 comes standard with a hydrofluoric acid and high salt resistant injection system, allowing users to confidently analyze various types of samples; (9) Disassembly and maintenance: A simple design that can be disassembled and maintained in just one minute, achieving the easiest maintenance.
