The Zetasizer AT combines Malvern Panalytical's industry leading Dynamic Light Scattering (DLS) technology with two decades of expertise in design and automation of process interfaces for analytical instrumentation.

The Zetasizer AT is a fully-automated nanoparticle characterization system, delivering lab quality results on-line and in a timely manner for process optimization.

  • Ability to monitor processes involving nanoscale particles or droplets in real time e.g. homogenization
  • Ability to track changes in particle size with time and determine when the end point is reached
  • Automated sampling system facilitates sample extraction, degassing and dilution to the required concentration minimizing operator input
  • Sampling system designed to minimize sample consumption
  • Easy transfer of laboratory DLS methods to on-line system
  • Utilizes Malvern's Universal Interface for system integrators (Malvern Link II)

An automated sample preparation system utilizes high precision pumps and flow control valves to extract a sample out of a process pipe or vessel and dilute it to the required concentration. The sample is then degassed and pumped through the analyzer’s flow cell. After analysis the sample is discharged and the cycle repeats. Results are immediately available on the screen of the system computer and can be linked to plant SCADA or LIMS system.


Malvern Link II software controls every aspect of the sampling, dilution and degassing steps using Standard Operating Procedures (SOPs).

The Zetasizer AT also allows easy batch measurements of samples from other areas in the process, effectively doubling as a laboratory system.
