Purity control of Amino Acids – Polarimetric Method

Amino acids are the building blocks of proteins and therefore important components in many pharmaceutical products and foodstuffs.  At the same time, regulations and requirements for the purity of the substances are becoming stricter.

Amino acids are essential molecules for building proteins (e.g. carnitine is metabolized from lysine and methionine). They have an active amino- and carboxylic acid group which comprise stereo-isometric, or chiral, centers. These geometries are responsible for the optical activity of these chiral molecules. Polarimetry is a non-destructive and sensitive method for determining optical activity.

With SCHMIDT + HAENSCH VariFamily polarimeters with integrated Peltier thermostatization and full 21CFR_part11 compliance, we offer state-of-the-art instruments for this application.

Application area:

– Development of food supplements

– Quality control and process optimization
