3 Terms and Definitions

GB/T 4470-1998 and established the following terms and definitions apply to this standard. 3.1 Flame will analyze the analyte in the sample into free atoms, by measuring the vapor phase of the ground state atoms of the element electrical characteristics Magnetic radiation to determine the absorption of chemical elements method.

4 principle of the method

Light radiated from the measured elements characteristic wavelengths of electromagnetic radiation (light), the sample vapor produced by flame atomic systems, steamed Gas analyte ground state atomic absorption. Under certain experimental conditions, the relationship between absorbance and concentration of the analyte in the sample line with Lang Bo - Beer law. A = lg0tr = K Absorbing optical path length; ρ is the concentration of the analyte). Laws can be quantitatively analyzed.

5 Reagents and materials

5.1 Reagents The standard reagent in the absence of other specified requirements, refer to AR or more analytical reagents. Sample processing is often used inorganic acids such as. hydrochloric acid, nitric acid, perchloric acid, hydrofluoric acid, etc., should be checked before use, as far as possible to ensure that it does not contain yet Measuring metal element.
