Spectrocertified® Grinding and Briquetting Additives

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.

ADDITIVE	PROMINENT CHARACTERISTICS
X-Ray Mix™	General purpose grinding agent. Balanced for abrasiveness and lubricity to aid in grinding dissimilar particles of moderate hardness for relatively short times. Highly "plasticizes" and firmly bonds samples together under briquetting pressure. Available in pre-weighed tablets for ease of dispensing.
SpectroBlend®	A 44µ powder well suited for blending and as a diluent for high concentrations. Well balanced with abrasive and lubricious constituents for grinding most sample materials emphasizing difficult-to-process samples requiring long grinding cycles in metallic comminution vials or dishes. Resistant to degradation by thermal and irradiation exposure. Samples have "plasticized" surfaces. Available in bulk powder and ½ gm pre-weighed tablets for ease of dispensing.
Boric Acid	Abrasive substance for processing samples with strong re-welding tendencies. Sample pellets are fair to moderately bonded together. Frequently used in conjunction with other additives to impart increased abrasiveness to the grinding process.

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.
