JJF 1574-2016 《Program of Pattern Evaluation of Atomic Absorption Spectrophotometers》 Related products

JJF 1574-2016 "Atomic Absorption Specphotometer Type Evaluation Outline" is applicable to the type evaluation of atomic absorption spectrophotometer with classification code 46121500. The standard describes in detail the working principle and main components of atomic absorption spectrophotometer, including Light source, Atomizer, monochromator and detection system. The instrument is suitable for the analysis of various elements by using absorption characteristic wavelength radiation for quantitative and qualitative analysis after atomization of elements in the sample. Atomizer is mainly divided into two forms: flame and graphite furnace. The measurement of element content in the sample is based on the absorption wavelength and concentration difference of different elements. This standard refers to the relevant analytical instrument environmental test methods and atomic absorption spectrophotometer standards to ensure the accuracy and Reliability of the evaluation process, which is suitable for quality control and testing needs in scientific research laboratories and industrial production.
