The arc flame generated by the excitation of optical system is directly introduced into the vacuum optical chamber by the lenswhich realizes the optical path through and effectively reduces the loss of the optical path.
JB-750 Optical Emission Spectrometer has high sensitivity which is up to 1ppm. The accuracy is very high especially the content range of elements is less than 0.1%. This test method is much higher than other methods. It can simultaneous multielement analysis.
