        How to choose a metal spectrometer?

        Spectrometers are widely used in foundry and manufacture industries. But when you need one, how to choose a fit spectrometer , many things you should be considered.

        Understanding your requirements

        Help you control cost by constantly improving your products quality. A metal spectrometer can measure the elements and the elements range of your products.

        If you need an instrument in lab , the stationary spectrometer is suitable, a mobile spectrometer can be used in the workshop and field,  handheld spectrometer has its obviously advantage by the small size if you can tolerant lower precision.

        Wavelength range and Resolution

        They are two crucial parameters to examine a metal spectrometer. A typical spectrometer has several wavelength ranges : 130nm-800nm, 170nm-800nm, 170nm-650nm. The application requires different wavelength. Theoretically, a wider wavelength could detect more elements. The resolution is proportional to the accuracy of the instrument.

        Detector

        The manufactures of spectrometer always choose PMT/ CCD /CMOS detectors. In early times ,  PMT detectors are the mainstream choice, however ,the disadvantage of PMT detector is obviously, one detector can only corresponds one element to test, it is hard to add extra detector. Digital cameras led to the invention of CCD detector, it occupies the main market. This kind of detector can receive all spectrum, If you want to detect additional elements , only upgrade the software system . CMOS device used widely in phone cameras, but the lower pixels resolution makes it a second choice of spectrometer.

        Size

        The size of spectrometer determined by the size of light chamber, generally, chamber with PMT device has a larger size and CCD/CMOS device has a smaller size.

        Cost

        If you need a low cost and high precision spectrometer, the instrument made in GLMY is your best choice.

        Service

        The service is a significant factor to be considered, highly skilled service group provides professional after-sales service.
