Description
The PMI Filtration Media Analyzer is designed to meet the through-pore measurement needs of the filtration industry. The Filtration Media Analyzer provides fully-automated analysis of bubble point, pore size distribution, mean pore size, gas, liquid, and Frazier permeability, filter integrity and hydro-head. Testing under compression, tension, and elevated temperature is also possible, thereby allowing the user to simulate actual operating conditions.
Principles of Operation
A fully wetted sample is placed in the sample chamber and the chamber is sealed. Gas is then allowed to flow into the chamber behind the sample. When the pressure reaches a point that can overcome the capillary action of the fluid within the pore (largest pore), the bubble point has been found. After determination of the bubble point, the pressure is increased until all pores are emptied of fluid, i.e., considered dry. Gas pressure and flow rates through dry samples are also measured.
Applications
PMI's Filtration Media Analyzer is designed to meet the needs of the filtration industry -- both in the R&D and quality control environments. The Filtration Media Analyzer characterizes a wide range of filter media, including microfiltration and ultrafiltration membranes.
