Overview
What is heavy metals and trace element analysis?
Trace metal analysis allows detection and identification of low levels of metals in a sample which can be critical to product development, quality control and regulatory compliance. Determining trace levels of metals in samples can also help identify contaminants and provides important data to help both process improvement and chemical product formulation development. In a range of products, such as, pharmaceuticals, chemicals, cosmetics, medical devices and consumer products, it is important to understand which trace metals are present and the levels at which they are present in the sample.
This is critical as trace metals can impact a product’s toxicity and also affect how the substance interacts with other chemicals. Working at trace levels, the quality, performance and sensitivity of the analytical instrument is critical. Typically, trace level analysis requires experienced staff to operate highly selective technology using accurate and reliable methods. Chem-Tech® Laboratories provides responsive trace metals analysis services, available to parts per million (ppm) & parts per billion (ppb) detection levels.

Technical review
Common material and compliance considerations
Material identification
The product construction and material groups must be identified so that preparation and analytical scope remain representative.
Restricted-substance scope
Only substances covered by the confirmed requirement and agreed analytical scope are evaluated.
Screening and confirmatory analysis
Screening and quantitative methods serve different purposes and are selected according to the material and reporting requirement.
Compliance interpretation
A compliance conclusion requires the applicable requirement, reporting unit and decision limit to be confirmed.
Published laboratory capability
Tests and test methods
The methods below are matched to Chem-Tech's controlled technical test lists and published laboratory capability. The final scope is confirmed for the sample, specification and current laboratory capability.
| Test / parameter | Published test method | Technical purpose | Interpretation / high-low context |
|---|---|---|---|
| Lead (Pb) | IEC 62321-5:2013 / IEC 62321-3:2013 (XRF) | Measures or evaluates lead (pb) under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. |
| Cadmium (Cd) | IEC 62321-5:2013 / IEC 62321-3:2013 (XRF) | Measures or evaluates cadmium (cd) under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. |
| Mercury (Hg) | IEC 62321-4:2017 / IEC 62321-3:2017 (XRF) | Measures or evaluates mercury (hg) under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. |
| Hexavalent Chromium (CrVI) | IEC 62321-7-2:2017 / IEC 62321-3:2017 (XRF) | Measures or evaluates hexavalent chromium (crvi) under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. |
Before dispatch
Sample-submission guidance
- Use a clean, secure and appropriately labelled container.
- Provide the sample identity, fluid grade and equipment or system details where applicable.
- Share operating hours, maintenance history, the suspected problem and required specification where available.
- Contact Chem-Tech before dispatch so the laboratory can confirm the sample quantity, container and selected testing scope.
Technical output
Reporting and interpretation
The report records results and methods for the agreed scope. Customer-supplied limits or specifications can be considered when provided before testing.
Results should be reviewed with equipment history, operating conditions and previous data; a laboratory result alone does not guarantee a root-cause diagnosis or remaining service life.
