PG Instruments AF400 Simultaneous Atomic Fluorescence Spectrometer provides elemental analysis for sub trace detection of hydride-forming elements. The design and functionality provides enhanced sensitivities and reduced interferences for parts per trillion (ppt) detection of Mercury (Hg), Arsenic (As), Cadmium (Cd), Zinc (Zn), Bismuth (Bi), Selenium (Se), Tellurium (Te), Antimony (Sb), Tin (Sn), Germanium (Ge), and Lead (Pb) .
The AF400 utilises a unique optical configuration that increases fluourescence intensity and improves detection limits. This arrangement allows approximately twice the fluorescence intensity commonly found on traditional AFS systems.
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 up to 3 elements or ultra high sensitivity.
