Bubble Point Measurement Settings
Exclusive SmartFlow technology
provides unrivaled accuracy and repeatability in bubble point determination.
The AccuPore employs the unique controlled-flow method to
apply a steady flow of gas to the surface of the wetted membrane, precisely
increasing pressure. A deviation from a linear increase in pressure is
associated with the onset of pore opening and marks the bubble point. This
method drastically increases accuracy and resolution of bubble point
determination compared to common bubble point estimates.
To optimize bubble point pressure resolution, the pressure is
increased more slowly if the expected pores are large (lower pressure) and more
quickly if the expected pore size is small (higher pressure).
Select the Pore Size range that best describes
your sample. For subsequent measurements, adjust your selection to better match
your understanding of your material. If you aren't sure, a small pore scan will
be a relatively quick estimate, then you can repeat as needed to achieve your
required accuracy.
