Abstract

An atomic absorption spectrophotometer uses optically encoded hollow cathode lamp assemblies (HCL1-HCL4). The code represents one or more atomic elements corresponding to their resonant line(s), and is read by corresponding optical code readers (OCR1-OCR4) 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 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 optical code may be for example a bar code and may be directly affixed to the lamp envelope or on a separate card attached to the lamp, the card being inserted into a card reader. <IMAGE>
