Product Overview

The Malvern Zetasizer AT is an on-line nano particle sizing system. The system uses Dynamic Light Scattering (DLS) measurements to allow real time optimisation of nanoscale particle processes.

The automated sample collection system extracts a sample out of a pipe or vessel and dilutes it to the required concentration. The sample is then degassed and pumped through the analyser’s flow cell. After analysis the sample is discharged and the cycle repeats. Results are immediately available on the system computer and can be linked to plant SCADA or LIMS systems.

Malvern Link II software controls every aspect of the sampling, dilution and degassing steps. It also allows easy batch measurements of samples from other areas in the process, effectively doubling as a laboratory system.
