The amount of water vapor taken up by an active pharmaceutical ingredient (api) as a function of relative humidity is routinely evaluated to characterize and monitor its hygroscopicity throughout the drug development process. Boil gently for a few minutes and siphon off the aqueous. The study was undertaken to develop a suitable design to accommodate liquefying hygroscopic samples in the proximity equilibrium cell (pec) for equilibration to.

By determining whether apis are sensitive to moisture, our scientists will help you to make a decision for operational and procedural conditions that can ensure the physical and chemical. The general notices indicate that the statements included in the characters section are not to be interpreted in a strict. The article tries to educate the reader about how the indian patent office ascertains the presence of inventive stepnon obviousness of a proposed invention. Recently, determination of the hygroscopicity is of great importance to select the most appropriate solid form of a drug substance for development.

Hygroscopicity is the measurement of a material�s ability to absorb or release water as a function of humidity (ie water activity). These results strongly support the belief that. Hygroscopic materials will generally be supplied in sealed bags to reduce moisture absorption but even sealed bags will pick up moisture if stored in a moist cold area. The gold source test.
