6700: SpectroStandards® XRF Reference Material Preparation Kit

In the absence of readily available standards, the SpectroStandards^® XRF Reference Materials Preparation Kit offers an alternate choice in accommodating infrequent or out-of-the-ordinary unknowns. The unique assemblage of assorted compounds representing 50 elements to prepare in-lab reference materials for single or multiple elemental analyses.

The method involves gravimetric dilution of a compound with a diluent, e.g. 44 µm SpectroBlend^® Powder to develop a weight percent concentration value of the element of interest. Two sample vials of 44µm SpectroBlend^® Powder each containing 6 gm is included with each Kit. Successive dilution preparations serve in establishing a linear correlation of the concentrations and analyte-line intensities against which the unknown sample is referred to and assigned a concentration value. Kit includes instructions for loose powder and pelletized preparations.
