Malvern Zetasizer Nano ZS

 

Summary

The Zetasizer Nano ZS is a high performance two angle particle, zeta-potential, and molecular size analyzer for the enhanced detection of aggregates and small particles.  Samples may be measured at very low or high concentration using dynamic light scattering with ‘NIBS’ optics.  Size may be measured in the range of 0.3nm to 10um.  Zeta-potential may be measured in the range of 3.8nm to 100um.  The flow mode option enables the system to be connected to an SEC or an FFF system to use as a detector for the size of proteins or nanoparticles.  The MPT-2 Autotitrator allows the study of the effect of changes in pH, conductivity, or any additive to be automated.  A range of disposable and reusable cells are available to optimize the measurement in terms of sample volume, concentration and flow measurement.

The instrument is located in 1238 Hach Hall.  Enquiries should be directed to Steve Veysey.  Phone 515-294-5805 (office).  Use "Booked" to reserve time.  Reservations do not need to be approved.
