Custom Preparation

Besides our already produced Reference Materials, ITAK offers a Custom Preparation service for Reference Materials. This service allows for the preparation of Reference Materials using the client’s own matrix, fully customized according to the specific needs of each project. This practice significantly reduces the matrix effect in chemical analyses, resulting in a substantial improvement in the quality of QA/QC controls and protocols, and analytical calibrations.

Custom preparation brings several benefits to our clients, such as:

  • Technical Advantage: Enables monitoring analyses with Reference Materials of the same geochemical matrix as the samples, providing more accurate and similar parameter tracking.
  • Operational Advantage: Ensures longer usage of the same Reference Material in QA/QC, optimizing operational processes.
  • Commercial Advantage: Offers more affordable values compared to ready-stock reference materials, providing a more economical option for our clients.


To evaluate the preparation of Custom Certified Reference Materials from the client’s matrix, ITAK requires information provided through the following form:
