Certain elements may have to be excluded due to matrix interferences. Please contact the laboratory for the best digestion method for solid samples.

Multi-element screening is intended to provide information on which elements can be detected in a sample and on their approximate concentrations. In the screening a combination of ICP-AES and ICP-SFMS is used. About 70 elements are determined, partly by using "single-standard analysis". Multi-element screening can be used as a basis for selecting elements for subsequent quantitative analysis.

| Figures in brackets denote limits of quantification in µg/l for pure water. Minimum sample amount: 60 ml. Hydrofluoric-, nitric- and sulfuric acids can also be analyzed. Reporting limits depends on concentrations of acids etc. Contact the laboratory for a discussion. |
|
|
| E-2a may be supplemented with additional elements: Be, Li, Sn, Ti, U and V. |
| Special analysis can be made on other sample types with lower limits of quantification than specified in the packages Contact us for discussion. |
