Description
Fischer X-ray Fluorescence (XRF) measuring devices are continuously optimized to achieve higher precision in shorter measurement times. That is why we have developed our new digital pulse processor DPP+ completely in-house. The DPP+ is one of the central elements of an X-ray fluorescence spectrometer which processes high count rates.
Features:
– Modern Silicon Drift Detector (SDD) for high accuracy and a good detection sensitivity.
– High-resolution colour video camera for precise determination of the measurement spot.
– Bench-top unit with upward opening hood.
– Detector: new SDD detector with 20 mm2 ( 160 eV )
– Micro-focus tungsten tube with beryllium window
– Fitted with the new Digital Pulse Processor (DPP+)
Application:
– Jewellery, precious metals and dental alloys.
– Precious Metal Analysis eg. Gold, Silver and Platinum group elements such as Iridium, Ruthenium, Osmium, Rhenium.
– Measuring coating thickness on sterling silver, rhodium finishes or gold alloys
– Determination of complex multi layer-coating system
