Bubble Dynamics -
The micro-bubbles in the foam behave as deformable
solids. As they travel through the filter they move as a rigid body.
•
Exfoliating Action -
As the micro-bubbles in the foam impact against each
other and burst, the turbulence and energy produced helps to lift particles
that are adhering to the filter fibers.
•
Buffered Elution -
The buffered elution fluid is conductive and breaks down
the electrostatic charges holding the particles to the electret filter,
effectively releasing them in the liquid sample.
