"JJF 1695-2018 Atomic fluorescence photometer type evaluation outline" is suitable for evaluating the type of non-dispersion Atomic fluorescence photometer with classification code 46621000. This outline refers to JJG 939-2009 "Atomic fluorescence photometer", GB/T 11606-2007 "Analytical instrument environmental test method" and GB/T 21191-2007 "Atomic fluorescence Spectrometer (AFS) " and other relevant standards. Atomic fluorescence photometer emits characteristic radiation light through the Light source to illuminate the atomic vapor of the measured element, and when it is excited to return to the ground state or low energy level, the radiated fluorescence is received and measured by the detection system to achieve quantitative analysis. The instrument is composed of key components such as Light source, vapor generation system, Atomizer and detection system, and mainly relies on Photomultiplier for signal amplification and detection.
