AF400 Simultaneous Atomic Fluorescence Spectrometer


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.
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.
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.
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.
Quartz Atomiser; The quart atomiser is selected for durability and long life operation.
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.
