Osmolarity measurement
Determination of osmolarity of liquid samples using a freezing point osmometer according to the European Pharmacopoeia method Ph. Eur 2.2.35.
Osmolarity is defined as the number of osmols per liter of liquid, reflecting the total number of dissolved ionic and molecular substances present in the solution in molarity.
The results of the analysis are reported in mOsm/L.
NOTE: The total concentration of the solute in the product needs to be provided (expressed in g/mL), as this information is necessary for the calculation of osmolarity. Without this information, only the product's osmolality (mOsm/kg) can be determined.
If the product is a powder, please provide instructions for the preparation of the solution.
Analysis can also be performed under GMP - please ask us for an offer.
