The light source used in Atomic Absorption Spectroscopy is unique. It looks like any other lamp but its uniqueness lies in the fact that its cathode is made of the same element which you have to determine in your sample. This means that you have to use a different lamp for every element whose analysis is required. Light sources in Atomic Absorption Spectroscopy briefly provides introduction to LARK® hollow cathode lamps and LARK® multi element hollow cathode lamps.
