Method and system for X-ray fluorescence (XRF) analysis of exploration samples

A collector device for determining a metal in an exploration sample containing a concentration of the metal not directly detectable by X-ray fluorescence (XRF), comprises an adsorbent material capable of concentrating metal from a digestion mixture produced by digesting the exploration sample, which is configured for association with an analysis window of the XRF detector to facilitate determination of the amount of metal value in the exploration sample. A sample preparation vessel, method and system used to prepare exploration samples for analysis includes a vessel for receiving the exploration sample, a digestion tablet and a digestion medium; a closure to allow the vessel to be agitated to produce a digestion mixture comprising dissolved metal and the collector device. The closure and the collector device are coupled so that collector device is retrieved from the vessel by removing the closure. The digestion tablet includes a metal lixiviate and an alkali compound.

The invention provides a novel microfluidic platform for use in electro-crystallization and electro-crystallography experiments. The manufacturing and use of graphene as X-ray compatible electrodes allows the application of electric fields on-chip, during X-ray analysis. The presence of such electric fields can be used to modulate the structure of protein (or other) molecules in crystalline (for X-ray diffraction) or solution form (for X-ray scattering). Additionally, the presence of an electric field can be used to extend the lifetime of fragile samples by expediting the removal of reactive secondary radiation damage species.
