The table below provides information about common isotope ratio analyses provided by ALS. The complete list of analytical capabilities as well as list prices for single sample orders can be found here:
Please request a quote for orders of batches of samples and/or continuous projects.
What is included in the analysis?
The basic analytical packages include standard sample preparation techniques, dilution and isotopic analysis by ICP-SFMS. Our top-of-the-line products typically include:
- Customized sample preparation; matrix removal and analyte pre-concentration, with recovery and purification verification by multiple ICP-SFMS analyses
- Isotopic analysis by MC-ICP-MS.
- We also have options for customers who have the capability to provide purified solutions ready for the final analysis.
