Abstract
An atomic absorption spectrophotometer uses hollow cathode lamp assemblies (HCL1-HCL4) encoded by means of recesses and/or projections. The code represents one or more atomic elements corresponding to their resonant line(s). The presence or absence of the projections and/or recesses is read by corresponding code readers (CCR1-CCR4) feeding a microcomputer (MCP), which includes a microprocessor ( mu P) a read-only memory (ROM) and a read-write memory (RAM) to identify the elements. The read only memory (ROM) contains wavelength information at a location associated with each element, by means of which the microprocessor causes the correct operating current to be supplied by the lamp power supply (LPS) and causes the monochromator (MN) to be driven to the appropriate wavelength by the monochromator wavelength control (MWC). The projections and/or recesses may be formed in the lamp base or in a separate card attached to the lamp and inserted into a card reader. <IMAGE>
