Most powdered sample substances are considered multi-phased or compositionally complex. They are comprised of individual particles or crystal phases frequently dissimilar in composition, density, hardness, configuration, size and distribution. Each particle tends to behave as a separate entity from its surrounding constituents. Chemplex grinding and briquetting additives are formulated to aid in the grinding and briquetting process by reducing particles to a uniform size and distribution forming a homogeneous sample blend for XRF analysis. Under briquetting pressure, the powdered samples are transformed into "plasticized" pellets with smooth unblemished surfaces resistant to inadvertent chipping or flaking apart. Samples may be saved for future referral.

Boric acid contains abrasive substances for processing samples with strong re-welding tendencies. Sample pellets fairly to moderately bond together. Frequently used in conjunction with other additives to impart increased abrasiveness to the grinding process

Preparing Samples

In preparing powdered samples requiring a grinding or briquetting additive, it is most advantageous to use the least amount of additive to minimize the effects of dilution unless the use of the additive is for dilution purposes.

As a starting point, use 1.0 to 2.5 wt % additive of the sample weight, e.g. 0.1 to 0.25 gm additive, to 10 gm sample. Adjust the amount of additive until the desired results are obtained. Alternatively, the additive weight may be held constant and the sample weight quantity varied for applications that will be utilizing the convenience of pre-weighed tablets. To maintain compatibility, standards should be similarly prepared.

Note: Some additives may reportedly contain trace elements that may potentially interfere with a given analysis. It is suggested that a "Blank" is run to evaluate the presence and interference level prior to an analytical investigation.
