Case Study: Stability Study Moisture Permeation

Dry pharmaceutical product needs to be protected from moisture to achieve an optimal shelf life. Sterile injectable products such as freeze dried formulations or dry powders are therefore often sealed in stoppered vials under dry nitrogen. However, over the shelf life of the product it is possible for moisture to permeate into the vial. Download this Case Study to see how moisture permeation can be measured using rapid, nondestructive, laser-based headspace analysis.
