A multivariate method to predict the water vapour diffusion rate through polypropylene packaging.

Semipermeable containers typically allow water to diffuse upon storage. The water diffusion rate of the widely distributed X-ray contrast agent Visipaque in polypropylene bottles and MR contrast agent Omniscan in polypropylene syringes has been evaluated. The goal was to develop a mathematical method for estimating the rate constant for water diffusion… CONTINUE READING
