Total reflection X-ray fluorescence spectrometry

Atomika 8030C is a commercial TXRF spectrometer for qualitative and quantitative chemical analysis of liquids and qualitative analysis of particulate samples. Sample loading may be automated (up to 70 reflectors). Mo-Kα, W-Lα and –Lβ or bremsstrahlung with 32 and 35 keV from a 2.5kW Mo-W X-ray tube can be used for excitation. The high-energy bremsstrahlung photons allow measuring higher-Z-elements via their K-lines (e.g. Cd). Detection limits for medium Z elements are in pg range (µg/L).
