Dynamic Vapor Sorption for the Determination of Moisture-Induced Glass Transition in an Amorphous Pharmaceutical

A new method to determine the onset relative humidity for a glass transition in an amorphous material was developed using the DVS. Water vapour can act as a plasticising agent in amorphous materials, causing a recrystallisation event below the glass transition temperature. This method calculates the threshold relative humidity for this moisture induced glass transition at a particular temperature.

Use of Optical Microscopy for the Investigation of Dried Milk Powders under Varying Humidity Conditions

The effects of humidity are evident in the stability and shelf-life of a variety of materials, formulations, and processing behaviour, especially food materials. This article discusses the advantages of a direct comparison method of three similar dried milk samples under varying humidity conditions, using optical microscopy in conjunction with the GenRH-A accessory and Mcell from Surface Measurement Systems.

Using Inverse Gas Chromatography (iGC SEA) to Identify Variations in the Dissolution Rate of Pharmaceutical Drugs

Active materials with batch-to-batch variations present a major issue to the pharmaceutical industry. On the whole, any batch-to-batch variation is undesirable. The range of techniques available for the characterization, analysis, and discrimination of products that are chemically identical can be restricted by the nature of the materials, and the sensitivity to slight physicochemical variations between them.
