Save as SOP if you want to save these settings 13. Data Processing Choices depend on measurement type. Advanced These settings should be at the default and do not need to be changed. Measurement Set the number of runs per measurement to Automatic unless your sample is changing over time (fewer runs) or if it is somewhat polydisperse (more runs) More than one measurement is recommended to verify the consistency of your results. If the temperature is being changed from 25 C, or if your sample has recently been stored at a different temperature, give the sample 3-5 minutes to equilibrate. Temperature Temperature limits for cuvettes are listed on page 1 of these instructions. General Options Choices depend on measurement type. The NBTC has a viscometer and refractometer to assist with these measurements. If the dispersant you are using has not been listed, you will need to find the viscosity, refractive index, and (for zeta potential measurements) dielectric constant for that material. Dispersant Select the liquid your sample is dispersed in from the list. If the material has not been listed, you will need to find the refractive index and absorption for that material. Material Select the material you are measuring from the list. The data for this measurement will contain this label.
Measurement type: Size, zeta potential, or molecular weight.

#Malvern zetasizer nano za software
Start the Zetasizer software by clicking the DTS desktop icon: 4. Two final beeps will indicate the instrument has reached the default temperature of 25 C. When turning on the instrument, a beep will indicate the instrument has been turned on, followed by another beep when the instrument has finished the setup routine.
An unstable light source is more likely to introduce errors in the measurements. If the instrument is off, turn on the instrument and wait 30 minutes for the laser to stabilize. If needed, log in to the local instrument computer Username: zetasizer. Activate the instrument computer by logging in to the central login system in the service corridor.
