Description
MACHINE TYPE:
The Perkin-Elmer AAnalyst Model 300 atomic absorption spectrophotometer is a sophisticated instrument that allows for the determination of the concentration of many elements in both organic and aqueous solutions.
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 a specific spectrum of the element it is composed of. The light beam passes through an air-acetylene flame or nitrous oxide-acetylene flame, which has a specific high temperature and flow rate. The atomic source introduces the sample into the flame in aerosol form, 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 absorbed light into the actual concentration of the sample. The instrument in addition to AAnalyst 300 is equipped with:
- AS-90 Controller
- AA Accessory Cooling System
- HGA 850 Graphite Furnace
