NanoPlus Operator’s Manual Distribution Graph

Distribution Graph
The Distribution graph is plotted between Intensity, Mobility/Zeta Potential, and Frequency. You
can view the graph at all positions at which the zeta potential/mobility is measured. The positions
are set in the Cell Parameters of the Zeta SOP Designer. See
Cell Parameters Panel, page 3-25 .
Distribution Graph with Zeta Potential of the Sample
Doppler Shift (24.16 Hz.
Lorentzian Peak
Sample Zeta Potential
Blue line = Raw data
Red curve = Fitted data
To change the position: select the desired position from the Select Relative Position drop-down
menu at the top of the graph.
To switch from Zeta Potential to Mobility: click Mobility at the top of the graph. The name of the
button then changes to Zeta Potential , allowing you to switch back to Zeta Potential.
The pink vertical line represents the Doppler Frequency Shift of the signal from Base Frequency.
The Lorentzian Peak represents the Brownian motion of the particles. The number “1” indicates
the Lorentzian Peak number.
