XRF Spectrometer

Supply of a high-performance, fully automated, computer-controlled sequential wavelength-dispersive XRF spectrometer. The instrument should be capable of conducting, with high precision and accuracy, quantitative, qualitative and semi-quantitative (standardless) analysis from sub-ppm level to 100%, with the capability of analysing elements from boron through to uranium.

Supply, installation, commissioning and maintenance support of an X-Ray Diffractometer system with micro-diffraction capability and a large capacity sample changer. We also require a chiller which may either be an integral one or stand-alone. NB, limited space in the intended laboratory location for the XRD may require the proposed solution to fit within a given footprint. Suppliers are encouraged to arrange a site visit before preparing their bids.. Samples will be sent out to each of the bidders for identification and quantification; this will form an important part of the tender process.

The XRF must have the ability to analyse fused glass beads for major oxides over a wide variety of sample compositions (silicates, carbonates, clays, bauxites, soils, cements etc.), within a range of flux mixtures; 100% lithium tetraborate to 100% lithium metaborate and any mix of those two flux mixtures. The XRF must also be able to analyse pressed powder pellets for minor and trace elements from 1000’s ppm to sub-ppm levels.

The instrument should also have the option to analyse samples using and an Energy Dispersive (ED) detector as a screening tool for unknown samples.
