1, NITON, from America, has been engaged in the material analysis industry for more than 20 years. As a leader in the manufacturing of handheld X-ray fluorescence (XRF) analytical instruments, NITON has been leading the trend of handheld XRF technology.
Spectrum analyzer, high-quality imported testing instruments, the global industry, specializing in the sale of hand-held spectrometers, smart technology to use with confidence, portable spectrometers, widely used all over the world.
2. Spike Analytical Instruments, Germany, is currently the largest manufacturer of atomic emission spectrometers in the world. Founded in 1979, it not only inherits the tradition of manufacturing high-quality optical instruments in Germany.
Moreover, with its unique advanced technology, stable and reliable quality and thoughtful after-sales service, it has been in the leading position of emission spectroscopy technology in the world.
3. Italy GNR Company is a professional manufacturer of R&D and spectral analysis instruments, established in 1942 and headquartered in Milan, Italy.
The history of GNR spanning more than half a century almost coincides with the development of modern spectrometers, from early spectrometers to electron tube spectrometers, from direct reading spectrometers with computer technology to modern CCD direct reading spectrometers, from floor-mounted X-ray fluorescence spectrometers to hand-held X-ray fluorescence spectrometers.
4. Olympus spectrometer, enos portable X-ray fluorescence spectrometer has been widely used in geology, mining, metals, soil, environment, archaeology, petrochemicals, toys, large-scale projects, boiler manufacturing, renewable resource metals,
Daily analysis of glass recycling, criminal evidence identification and other fields. The products widely used by the United Nations International Atomic Energy Agency have played a role in Iraq's weapons inspection and Iran's inspection for many times.

Problems needing attention in purchasing hand-held spectrometer;
1, stability, stability of analytical instruments is very important, and standard samples should be input before ICP analysis.
Therefore, the test results generally do not deviate from the true value. The key is whether the results of similar samples are consistent after each analysis. Whether it is high or low, you will know which sample is qualified.
2, analysis speed, if it is a full-spectrum machine, generally 72 elements/minute, if it is a scanning type, the speed is slower. Now, except for some special industries, scanning is still used, and all others are full spectrum. It is not that scanning is not good, but that the technology is old and easy to be eliminated.
3. Wavelength range, whether it can cover the spectral range of all elements you want to detect.
4. Optical resolution (200 nm). Theoretically, the higher the resolution, the better. Of course, it depends on your sample.
5, failure rate, this is very important, it will not be used if it breaks down every day.
6, after-sales service, there is no machine that will never break down, and the quality of after-sales service is also very important.
