ATOMIC ABSORPTION SPECTROMETER – PERKIN ELMER – AANALYST 300

APPLICATION SECTOR: Pharmaceutical, chemical, cosmetic, food, dietary, medical devices.

FEATURES: The AA-300 is used to determine the unknown concentration of a single element by measuring the amount of light. The instrument readings are calibrated to directly display the concentration; the basic instrumentation requires a primary light source, an atomic source, and a detector. The light source is a hollow cathode lamp (HCL) or an electrode discharge lamp (EDL), which emits at the specific spectrum of the element it is composed of. The light beam passes through an air-acetylene flame or nitrous oxide-acetylene, which has a specific high temperature and flow rate. The atomic source introduces the sample into the flame in the form of aerosol, and the heat produces free analyte atoms. The analyte atoms in the flame that correspond to the particular lamp used absorb energy from the light source. A detector, usually a photomultiplier tube, measures the light intensity coming out of the flame. The electronics convert the amount of light absorbed into the actual concentration of the sample. The instrument in addition to AAnalyst 300 is supplied with:

• AS-90 Controller
• AA Accessory Cooling System
• HGA 850 Graphite Furnace
