Product Grades

The determined purity for an individual product can change slightly from batch to batch. The percentage grades shown on this webpage and in the catalog represent typical purity values, defined as shown below.

If possible, products are assigned to one of the grades shown below, based on the purity of the material. The analysis of the material and the method is defined in the product specification sheet or in the certificate of analysis.

Different numerical grades may apply to specific products. We reserve the right to adjust the product grades and specifications according to the stock availability of selected chemicals. If you require more information about the actual purity of our products, please email us at georganics@georganics.sk or use our contact form.

All ordered products are supplied with a full certificate of analysis (1H NMR, GC, HPLC, IR). Usually, we use the most suitable analytical method, but we can include other methods as required by our customers.
