The NRC will host a free workshop on particle size and zeta potential measurement using the Malvern Zetasizer Nano ZS instrument. Malvern scientists will be on hand to introduce light scatting concepts and demonstrate the tool with user-provided samples. Attendance at this workshop will constitute the initial training on this tool, which the NRC has available in the Marcus organic cleanroom. You do NOT need to be a current NRC user to attend.

The Malvern Instruments’ Zetasizer ZS measures particle size (0.3 nm to 10 μm) via dynamic light scattering (DLS) with backscatter optics and zeta potential using electrophoretic light scattering (ELS). This tool can also be used to measure molecular weight (as low as 342 Dalton). Aqueous and organic solvents can be used, with samples as small as 12 μl, and controlled temperature (0-90 ºC).

Workshop Agenda

Part I – Introduction

• Dynamic and electrophoretic light scattering: Introduction and basic theory  
• Zetasizer technology and measurements: What happens when I click "Start"? 
• What data do I get and how do interpret it? 

Part II - Hands-on Instrument Training

Attendees may bring one sample for training/demonstration purposes; however time limits will only allow 4-6 samples (first-come, first-served) to be analyzed.
