Sigmatik is the first private company in Poland engaged in the production of standards
of analytical organic substances and chemical reagents. Unlike other Polish companies on the market, we do not mediate in bringing standards from abroad – we create them in our laboratories in Wrocław.

In addition to the usual standards, reference materials or matrix modifiers, we also offer inorganic standards and unusual standards, produced specifically for the needs of customer.

Products currently available are present in our catalog. Questions about the evaluation of a custom order can be asked through our contact form.

Analytical chemistry is based not only on the proper preparation of test substances, but also on a statistical analysis of the results. However, there are substances which preparation for the research can be problematic. We are talking about highly hygroscopic substances.

Certified reference materials (CRM) are commercially available primarily in two forms:
as pure substances or solutions with a strictly defined concentration. The choice of solvent used in the solution mainly results from the physicochemical properties of the substance (e.g. solubility) and the limitations of the research method.

One of the aspects of the stability of solutions of certified reference materials is the content of ions of transition metal – such as iron and manganese. Ions, which have access to the air, can catalyze for expamle red-ox reactions, causing changes in the composition of the solution and may change the concentration of standardized substance in the solution.
