trace metals analysis

Trace Metals Analysis by ICPMS is also an excellent way to determine residual catalysts, such as palladium and platinum, in process intermediates and final

products. As an addition to trace metal analysis, we also offer full compendial API and excipient testing to the EP, BP, JP, and USP compendial.

In order to develop the best approach, the Metals Team begins by determining whether the application requires validated or non-validated methods. A fully validated approach may require multiple methods, depending on the material and metals. A critical step in determining the most appropriate analytical approach is to address the following key criteria:

  • Define need for a general screening method vs. specific elements of interest

  • Establish material specification limits as applicable

  • Evaluate material solubility

The following table will help determine the instrumentation that best meets testing needs and provide general instrument performance guidelines, which may vary by method. For example, sensitivity limits are dependent on sample digestion approach, sample mass and instrument wavelength.
