Isotopic Standards

 Elemental isotope standards for Isotope Dilution Analysis.

 

Certified Reference Materials (CRM) are provided with the following general characteristics:

  Certified concentrations:   10 - 100 ug/g
  Certified abundances (equal to or greater than 0.1%):   See product information
  Minimum isotope enrichment (if not speficied otherwise)*:   90%
  Maximum expanded uncertainty of concentration values (95% confidence level)*:   10% of the certified value
  Maximum expanded uncertainty of abundance values (95% confidence level)*:   0.4 %

*for specific information about the characteristics of a product, please contact us at isc_arroba_isc-science.com. The characteristics shown here are general for all products within this category.

Our Certified Reference Materials can be used in Isotope Dilution Analysis to: Determine the element concentration in other materials; Precision control; Bias control
