Abstract

An atomic absorption spectrophotometer uses magnetically encoded hollow cathode lamp assemblies (HCL1-HCL4) corresponding to their resonant line(s), the code being representative of one or more atomic elements. The code is read by corresponding magnetic code readers (MCR1-MCR4) whose outputs are fed to 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 therein 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 magnetic code may be on a label directly affixed to the lamp envelope or on a separate card attached to the lamp, the card being inserted into a magnetic card reader. <IMAGE>
