The AXIOS 4kW rhodium source wavelength dispersive X-ray fluorescence (WD-XRF) spectrometer is a LIEF-funded instrument installed in 2009 to complement our older PW2400 3kW rhodium source WD-XRF. The instrument can analyse elements from Na to U, as well as B, Cl and F. Our major element suite includes the following, plus loss on ignition (L.O.I.): Na, Mg, Al, Si, P, S, K, Ca, Ti, Mn and Fe. For trace elements please contact the XRF laboratory, as we have a range of different packages for various trace element combinations. Our B program is specifically setup to analyse glasses.
