Abstract
An improved source lamp assembly for use in atomic absorption spectrophotometers is described having encoded structures for identifying the atomic element of the source lamp assembly, as well as to represent lamp operating current. The encoding structures are formed by way of mechanical, optical, or magnetic means. In particular, a mechanical arrangement involves a plurality of projections and recesses, either formed relative to a base structure of the lamp assembly or relative to an attached card-like structure. A card reading device is used to read this card-like structure. These alternative arrangements can be also used relative to optical encoding or magnetic encoding.
