Malvern Mastersizer 3000

With the Mastersizer 3000 the particle size can be determined by utilization of the SLS technique. Particles with sizes ranging from 10 nm to 3.5 mm can be analyzed. With different dispersion-units, particles can be dispersed in air, water and solvents. By utilizing different measurement chambers, the volume of the dispersion and the amount of sample can be adjusted.

Malvern Nanosight NS300

Size distributions as well as nanoparticle concentrations of aqueous highly diluted dispersions can be determined. Two laser modules with wavelengths of 642 nm and 488 nm allow tailored measurements depending of the particle size and material.  With built in fluorescence filters (500 nm and 650 nm) it is possible to track fluorescent particles as well as non-fluorescent particles in solution. Temperature control from 20-50 °C and a syringe pump allow a precise and reproducible analysis. Particle size ranges from 10 nm to 1 µm.

Malvern Zetasizer Nano ZSP

Via dynamic light scattering the particle size and the zeta potential of nanoparticle dispersions can be determined. Scattering is detected at 13° and 173° in a temperature range of 0°C to 90 °C. Particle size is limited from 0.3 nm to 10 µm. An autotitrator allows the measurement of zeta-potential and size distributions while adjusting the pH-value.
