Good Stability Versus Good Tabletability

Good Stability Versus Good Tabletability: The Choice of Modification

Many pharmaceutical solids exhibit polymorphism, i.e., the ability of a substance to exist in different crystalline forms. The polymorphic form can have significant influence on pharmaceutical processing and can, for example, affect grinding, granulation and tabletability. A DSC measurement allows for the characterization of the present modification. Here, different modifications of paracetamol are distinguished by means of DSC.

How to use TGA for the quality control of carbon fiber-reinforced polymers

The determination of fiber volume fraction is crucial for the quality control of carbon fiber-reinforced polymers (CFRP) in order to ensure their favorable mechanical and physical properties for the use in aerospace, wind energy and automotive sectors. A new thermogravimetric testing method, published by Dominik Grund in the journal “Polymer Testing”, considers heating rate, analysis atmosphere and sample size to efficiently ensure high quality of the material. This editorial summarizes the steps for the use of TGA in the quality control of carbon fiber-reinforced polymers.

How seals provide information about their own wear

Monitoring Damage Development

Static sealing elements are subject to natural, thermo-oxidative or mechanical aging processes and must be replaced after a certain time. The condition for cost efficiency is that a sealing gasket should be used over its entire service life without having to invest in complex and expensive monitoring systems.
The simplest and smartest monitoring system is usually already present: the reinforcing filler, which can be electrically conductive. Successful implementation requires knowledge of the exact correlation between the mechanical and dielectric properties of the final product. The key to understanding these correlations lies in the application of the simultaneous DMA and DEA using DiPLEXOR® 500 N.
