Gas Input for Atomic Spectrometer
It is the amount of absorption that determines the concentration of a particular component. Typical gases used in AAS are Nitrogen and Argon. Every ground state metal absorbs light radiation (and. Specifications of gases needed are shown in the following table: There are two kinds of gas are required by GF-AAS, the inert gas and auxiliary gas. The pressure have to be controlled in the range of 70-200kPa. Guystav Kirchoff and Robert Bunsen first used atomic absorption—along with atomic emission—in 1859 and 1860 as a means for identify atoms in flames and hot gases. The HCL gives off light characteristic to the elemental wavelength being measured. ASD Intro & Contents - Introduction to and.
