The basic principle of atomic absorption spectroscopy (AAS) is to atomise elements present in a sample and to subsequently let the atoms interact with element specific light provided by a hollow cathode lamp. Different categories of lamps are available for Shimadzu's AA-7000 Atomic Absorption Spectrophotometer. Standard single element lamps and multi-element lamps support the deuterium background correction technique (BGC-D2). For superior background correction, Self-Reversal Method lamps are applicable (BGC-SR).
