Analytical methods are developed using HPLC and UHPLC techniques with different detection methods (DAD, MS) for quantification of active compounds in various samples. Developed methods are validated in accordance with the recommended guidelines for validation of analytical methods.


Stability testing of food supplements and cosmetics is performed following established guidelines. The tests of stability are specifically customized to each formulation of the individual product and are carried out in real time or at accelerated conditions. The goal is to confirm the physico-chemical stability, microbiological quality and compatibility of the product formulation with the packaging for the predicted shelf life under certain storage conditions. By performing stability tests, the manufacturer can ensure a safe, effective and quality products.    


Samples are prepared and analysed following high standards in order to provide accurate value of the measured active compound or any other analyte of interest. Our routine analytical offer includes determination of vitamins, small proteins and peptides, amino acids, glucosamine sulphate, coenzyme Q10, β-carotene, resveratrol, carvacrol, sulphoraphan, L-carnitine, caffeine, curcumin, artemisinin, active compounds of echinacea, various sugars and many more in various sample matrices.
