TYPE OF MACHINE:
The Perkin-Elmer AAnalyst Model 300 atomic absorption spectrophotometer is a sophisticated instrument that allows you to determine the concentration of many elements both in organic and in aqueous solutions.

SECTOR OF USE:
Pharmaceutical, chemical, cosmetic, food, dietary, medical devices.

FEATURES:
AA-300 is used to determine the unknown concentration of a single element by measuring the amount of light. Instrument readings are calibrated to directly display concentration; 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 a specific spectrum of the element from which it is composed. The light beam passes through an air-acetylene or nitrous oxide-acetylene flame, which has a high temperature and specific flow rate. The atomic source introduces the sample into the flame as an aerosol and the heat produces free analyte atoms. 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. In addition to AAnalyst 300, the instrument is supplied with:

AS-90 Controller
