JJG939-2009 Atomic Fluorescence Spectrometer GB/T 11606-2007 Analytical instrument environmental test method GB/T 21191-2007 Atomic Fluorescence Spectrometer For dated references, only dated versions apply to this specification; undated quotations The latest version (including all amendments) applies to this specification.

3 Overview

The atomic fluorescence photometer (hereinafter referred to as the instrument) works on the principle that the characteristic radiation emitted by the light source is illuminated. On the atomic vapor of the element under test, the ground state atom is excited to a high energy level, and the excited state atom returns to the ground state or lower energy level. At the time, the emitted fluorescence is received by the detection system and the fluorescence intensity is detected for quantitative analysis. The instrument is mainly composed of a light source, a vapor generation system, an atomizer and a detection system, as shown in Fig. 1. instrument The key components are photomultiplier tubes.
