Abstract It is well known that the preparation of metals and liquids for XRF analysis is fast, easy, and usually requires little strategy. The preparation of powder samples such as silicates, carbonates, slags, cements, ferro-alloys and other powdered materials however requires careful planning in the way of additives, lubricants, binders, dilution, backing and holders. The ratio of binder to sample must include forethought regarding the homogeneity of the briquette, the stability of the briquette, the cleaning and cleanliness of the grinding vessel, and the performance requirements of the analysis. The ideal situation would be to have one set of preparation materials, with only one sample to additive ratio suffice for all powder preparations. Various preparation materials and strategies are examined, and their usefulness toward achieving a universal preparation method considered.
