Description
The Varian 220 FS (Fast Sequential) is for flame-source atomic absorption analysis of aqueous solutions and vapors. This AA spectrometer operates in both atomic absorption and emission modes. The fast sequential system offers 4 lamp positions that can be selected in sequence; this allowing analysis of 4 elements for a given solution. The instrument is also equiped with the SIPS sample dispersement system which allows on-line calibration and sample dilution.
