Figure 4. Displaying duration data in the relative particle speed plot using an inverted unit (ms-1)
allows for intuitive comparisons of particle speed.
A particle speed plot with two different speed signals implies that the
suspension contains particles with different surface charges. A particle with
a larger negative surface charge will experience a greater attraction towards
the positively charged electrode in the lower fluid cell and will travel through
the pore at a greater speed than a more neutral particle.
The FWHM, or “full width at half maximum” is the blockade width (duration
in milliseconds) measured at the point of half of the maximum blockade
magnitude, shown as the horizontal pink bar in the centre of the blockade
above.
