Ultra-pure reagents for voltammetry
Voltammetry is used primarily for inorganic anion and cation analysis, but can also be used to determine various organic compounds. The most important fields of application for inorganic determinations are metallurgy, environmental analysis, food analysis, toxicology, and clinical analysis. This technique is also a preferred method for the determination of certain metallic species, such as Fe(II)/Fe(III) or Cr(III)/Cr(VI).
Solvents for Trace Metal Analysis
TraceSELECT™ Solvents for LC-ICP-MS Applications
Solstice Advanced Materials has developed high-purity TraceSELECT™ solvents for LC-ICP-MS analysis.
This is followed by UV spectroscopy, IC, and ICP-MS to ensure high chemical purity and high UV transmittance. The blank values for trace metals in these solvents are in the ppb range or lower.
International trends show metal speciation as an area of high research interest.
In the future, the speciation of biological samples will undoubtedly lead to the need to identify which organic molecules attract which metals in specific sample types.
ICP-MS is a superior detection technique for trace elements in general, but especially for elements of interest such as arsenic, selenium, cadmium, iodine, and others in chromatographic eluents.
Sample Preparation for Trace Analysis
TraceSELECT™ Ultra and TraceSELECT™
Ultra-pure acids, bases, and salts for fusion and wet digestion in environmental, water, and food analysis.
Sample preparation for trace analysis requires reagents of the highest purity.
TraceSELECT™ Ultra products for ultrasonic analysis at ppb and ppt levels are produced by sub-boiling distillation.
Sub-boiling is recognized as the best way to obtain high-purity acids.
The technique is based on evaporation of the liquid by infrared heating at the surface.
To maintain their purity, TraceSELECT™ Ultra products are supplied in PTFE PFA (fluoropolymer) bottles.
Water and orthophosphoric acid are supplied in preheated HDPE bottles.
TraceSELECT™ series acids, bases, and salts were developed for sample preparation and analysis in the ppb (μg/kg) trace range.
