Elemental analysis

Recommended sample quantity is 0.1 g. The sample is mixed with wax (as binder) and boric acid. This mixture is processed in the form of pellet (10 mm diameter) with the aid of a hand press and placed in an isolated chamber where a vacuum (%3C10 Pa) is made.

Wavelength Dispersive X-ray Fluorescence (WDXRF)

AXIOS Panalytical wavelength dispersive X-ray fluorescence (WD-XRF) spectrometer owned by the Center for Innovation and Technological Research in the University of Seville (CITIUS) (Figure 12). The main features of the device include: Rh anode (4.4 kW maximum power), 3 collimators (150 μm, 300 μm and 700 μm), 6 analyzer crystals (LIF200, LIF 220, PX-10, Ge111, PE002, PX-1) that allow qualitative and quantitative chemical analysis of elements from O to U in a wide range of concentrations (from main components to traces), a flow detector (for Z%3C29 elements) and a scintillation detector (for Z>29 elements).
