Simultaneous Atomic Fluorescence Spectrometer Features Integrated Exhaust System The configuration of exhaust system effectively decontaminates exterior pollution ultimately enhancing the accuracy of the measurements. The shielded optic design greatly reduces light interference and enhances the signal-noise ratio, increasing the sensitivity and precision of the measurement. Hollow Cathode Lamps High intensity hollow cathode lamps provide increased intensity and stability. The AF400 multi-channel technology allows lamp configuration to be changed to accommodate application specific requirements allowing either simultaneous analysis increasing efficiency of measurements or ultra high sensitivity. Optical Design The AF400 utilises a unique optical configuration that increases fluorescence intensity and improves detection limit. This arrangement allows approximately twice the fluorescence intensity commonly found in traditional AFS systems. Quartz Atomiser The quart atomiser is selected for durability and long life operation. Detection The integration of high quantum solar photomultiplier tubes ensures stability. Gas/Liquid Separator The high efficiency gas/liquid separator of hydride and Hg cold vapour minimising pressure fluctuations and improving measurement precision. PG Instruments Ltd, Alma Park, Wibtoft, Lutterworth, LE17 5BH. United Kingdom Sample Introduction An integral high performance XYZ auto sampler with 2×45 vial trays provides automatic sample introduction and dilution with superior repeatability. The efficient operation maximises throughput and provides consistent results. Reagent Compartment An integral drawer contains up to three reagent bottles with low level indicators.
