Total reflection X-ray fluorescence (TXRF)
Bruker S2 Picofox (2 instruments), lab 01.184

The S2 PICOFOX is a benchtop spectrometer for fast quantitative and semi-quantitative multi-element microanalysis of liquids using the principle of total reflection X-ray fluorescence spectroscopy (TXRF). Detection limits are in the ppb and ppm range, so that the technique is optimally suited for trace element analysis. 

Specifications:

• Element range: Mo excitation: Al to U (with exception of Mo to Ru)
• Concentration: ppb to 100 %
• Sample types: liquids
• X-ray tube: 50 W metal-ceramic, max. 50 kV, 1 mA air-cooled, Mo target
• Detector: Peltier-cooled Silicon Drift Detector
• Energy resolution <149 eV at 100 kcps
• Autosampler with 25 positions
