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.

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.
