Elemental Measurement Portfolio
Elemental Analysis
Choose the elemental measurement that matches the analytical question, from the concentration of named elemental impurities to the relative abundance of selected isotopes.
The service pages below describe defined pathways and their technical-review requirements. If the exact measurement you need is not listed, contact the laboratory to see whether another method can be supported.
Featured Services
Elemental analysis services for defined project needs
Start with the measurement that best fits the project question, then review its defined scope before requesting technical review. These pathways are starting points for discussing the elemental work your project requires.
Elemental concentration
Elemental Impurities (Class I)
Quantitative ICP-MS testing for arsenic, cadmium, lead, and mercury—the four elements commonly grouped as Class 1 elemental impurities.
Defined scope: arsenic, cadmium, lead, and mercury by ICP-MS.
Review Elemental Impurities (Class I)Comparative isotope measurement
Isotope Ratio Analysis
Project-scoped isotope ratio measurements for source comparison, authenticity investigations, and other material-characterization questions.
Project scope: isotope system, matrix, references, and comparison design are reviewed.

Use each service page to understand its defined scope
The portfolio connects related measurement services without treating them as interchangeable. The selected service page defines the current analytes or isotope question, matrix and reference requirements, result type, and interpretation boundary.
Elemental impurities
Start with the applicable impurity class or named-element scope and the limit, specification, and reporting basis the results need to address.
Isotope ratios
Start with the isotope system, comparison question, and suitable reference materials or data needed to interpret the result.
Complementary work
When a project needs concentration and isotopic information, identify both questions during technical review so the work can be scoped together.
Technical Review
Define the material, measurement, and decision
Share the context behind the request so the laboratory can identify an appropriate service or determine whether a different elemental method can be supported.
- Exact material, product, matrix, ingredients, and processing context
- Whether the question concerns concentration, isotope ratio, or both
- Named elements, impurity class, isotope system, or comparison question
- Applicable standard, specification, reference material, or prior dataset
- Required limits, units, reporting basis, or interpretation framework
- Sample count, available quantity, and requested deadline
