Malvern Mastersizer Makes Mixer Selection Easier

The often difficult challenge of selecting the right mixer for specific process applications is made easier when thorough testing is possible. At the Test & Development Center of Charles Ross & Son Company, a major leading manufacturer of mixing equipment, their Malvern Panalytical Mastersizer particle size analyzer is one of the analytical instruments used by customers during process simulations.

Provided as complimentary service, mixing trials at the Ross Test & Development Center located in Hauppauge, NY, are availed by customers from a wide range of industries and from around the world. Working at the test center with their own raw materials, customers simulate their processes using Ross mixing, blending and dispersion systems. The Mastersizer is applied during the course of process optimisation and verification, as an aid to selecting the proper mixing equipment and correct process conditions.

“The Mastersizer is used alongside viscometers, moisture balances and other analytical equipment, and is very helpful in proving and demonstrating our technologies, particularly our high shear and ultra-high shear mixers,” explains Christine Angos, Application Engineer at Charles Ross & Son Company. “Particle or droplet size measurements of dispersions or emulsions tell us if we are at the desired endpoint, whether we need to process longer, or if we should shift to a different type of mixer. Even when other physical properties are critical to the product’s quality, measured particle size often gives us a definite indication of success.”

Malvern Panalytical’s industry leading Mastersizer systems use laser diffraction technology to measure particle size in wet and dry samples. Ross product lines include equipment to mix liquid-liquid, solid-solid and liquid-solid formulations over a wide range of viscosities, attracting customers from all process industries.
