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.
