Silicon
Sampling & Analysis

Silicon comes in the form of black-to-gray lustrous, needle-like crystals.  It is used in the manufacture of concrete, brick, specialized enamels, and glass.

The substance enters the body through ingestion, inhalation, or skin/eye contact.  It can irritate the lungs and respiratory tract, producing coughing, as well as irritating the eyes and skin.

Please send, under separate cover, a sample (bulk) of your particular solvent for use as a reference standard. The bulk sample will be charged the analysis price. Additional analyses and fees may be required to determine the DE for results that do not match a common standard.
:
Reported results reflect elemental analysis of the requested metals. Certain compounds may not be solubilized during digestion, resulting in data that may be biased low.
:
Analyte is referenced in the published method. If more than one published method is cited, the analyte is referenced in at least one of the methods.
