摘要： 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.

摘要： An optical analyzing apparatus (20) for obtaining a quantitative correlation spectroscopy measurements of an analyte concentration in a multiple constituent sample (24). The optical analyzing apparatus (20) employs a correlation spectroscopy algorithm which uses preselected wavelength light energy from both the visible light spectrum and the near-infrared (NIR) light spectrum to analyze multiconstituent samples. The optical analyzing apparatus (20) comprises a light emitter mechanism (22) formed for irradiating the sample (24) with a predetermined first wavelength of light energy in the visible light spectrum and a predetermined second wavelength of light energy in the NIR spectrum. The first wavelength is selected to be active in response to the presence of the analyte while the second wavelength is selected to be active in response to the presence of at least one of the remaining constituents in the sample (24). A detector mechanism (50) is positioned to detect one of optical reflectance and transmissivity of the sample (24) after irradiation at the first and second wavelength, whereby the detected one of reflectance and transmissivity can be used in correlation spectroscopy algorithms to obtain a value of the concentration.
