The performance evaluation of a filter or a membrane often requires the characterization of fiber thickness and through-pores size. ALFATESTLab is equipped for these measurements thanks to a scanning electron microscope SEM coupled to a unique software called Fibermetric for automatic measurement of fiber thickness, and to various techniques for pore size distribution measurements.
In many industries, fibers are used according to their applications properties: for instance, fibers with high mechanical properties are used to reinforce materials, unlike those used in textile or medical fields. The choice of fibers material can then be guided by a rheological characterization, GPC and Light Scattering measurements, and subsequent evaluation of fibers can be performed with automated image sistem (Morphologi G3 from Malvern Instruments also uses a shape parameter dedicated to the fibers characterization).
Automatic Image Analysis Static Automated Image Analysis is the ideal technique to obtain, through high quality images on statistically representative numbers of particles, accurate information about particle shape (circularity, elongation, […]
