通用粉末材料样品制备方法(XRF分析)

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. SPEX 3636全自动压片机
