A range of ‘on-demand’ presentations on the Malvern Instruments website provides expert guidance for analysts involved in making rheology measurements. These include ‘best measurement practice for capillary rheology’, and guides for making dynamic or oscillatory measurements on a rotational rheometer, focusing on ‘good measurement practice’ and ‘avoiding measurement artefacts’.
‘Best measurement practice for capillary rheology’ provides tips and guidance to ensure precise, accurate testing every time, from sample loading to basic instrument control through to more advanced measurement options, company claims.
For dynamic or oscillatory measurements on a rotational rheometer, ‘good measurement practice’ deals with ways of increasing the oscillatory measurements by explaining some methods of good practice, in particular, the linear viscoelastic region and its importance, and stress vs strain oscillation. A separate presentation ‘avoiding measurement artefacts’ discusses ways of minimizing errors and obtaining reliable data.
Also available are a basic introduction to rheology and presentations illustrating the link between rheology and particle properties, such as size distribution, shape and zeta potential.
