What is TCT?

Ion Chromatography Standards

If you've been searching for an atypical Ion Chromatography standard, look no further. Over the years, we've developed the most complete line of IC standards on the market. Our technicians have stabilized more than a dozen rare anion and cation standards that you won't find anywhere else.

Standards you can trust


We use NIST Standard Reference Materials (SRM and lot number specified on the certificate) for calibration and direct comparison.


We have detailed Error Budgets that define the errors used in determining the uncertainty, giving us a unique value for each lot of material.


We use ICP and ICP-MS to check the purity of all CRMs. Protocols are prepared for all new starting materials. We perform purifications and chemical modifications as required to meet predefined quality specifications.


We use two independent validated assay methods that are performed with a reliable QC standard.

Stable & Compatible

We've conducted stability studies on all standards, including blends. Compatibility and stability have been demonstrated and fully documented.
