The atomizer provides the thermal energy necessary to dissociate chemical compounds, thus providing free analyte atoms so that atomic absorption can occur. The difference between the two measurements yields the atomic absorption. The continuum source measures only the background. The primary source measures a combination of background and atomic absorption. When the continuum source background corrector is used, two alternating sets of measurements are made: one with the primary source and a second with the background corrector source. The spectrometer uses a deuterium arc lamp to correct for background absorbance caused by non-atomic species in the atom cloud. The electrical signal is amplified and processed to produce a signal which is a measure of the light attenuation occurring in the sample compartment.
The light leaving the monochromator is directed onto the detector, a photomultiplier tube (PMT), which produces an electrical signal proportional to the light intensity. Performance over the entire atomic absorption wavelength range. A dual-blazed grating is used, which provides excellent The monochromator disperses the various wavelengths of Iight and isolates the particular line of interest. The light passes through the sample compartment and is absorbed by the atomized sample. The primary light source, either a hollow cathode or electrodeless discharge lamp, is placed in the spectrometer to emit the narrow atomic lines of the element to be determined. To perform this function, the spectrometer uses a primary light source, a monochromator, and a detector. The spectrometer provides a means of measuring Iight at a specific wavelength. The following sections provide a general discussion on the theory of operation and a description of the components of the system, the atomizers, and accessories available with the AAnalyst 100 Spectrometer. The optional High Sensitivity GemTip nebulizer is available for those applications requiring the utmost in sensitivity and detection limits.īuilt-in gas controls with safety interlocks, automatic ignition button on the keypad, and automatic switching from an air-acetylene flame to a nitrous oxide-acetylene flame, simplify operation while insuring operator safety.Ī built-in control panel, with a two-line alphanumeric display, a numeric keypad, and function keys, is used to access the comprehensive programming which is embedded in the built-in microprocessor.
