Description
The characteristics of porous material are unique and often very complex. The customer desires to test his unique porous material and measure the pore structure characteristics relevant to his applications. Therefore, a custom porometer designed to meet the specific requirements of a customer is appropriate and economical.
Principles of Operation
A wetting liquid is allowed to spontaneously fill the pores in the sample and a nonreacting gas is allowed to displace liquid from the pores. The gas pressure and flow rates through wet and dry samples are accurately measured and the pore structure characteristics are computed.
Applications
The Porometer is a versatile instrument capable of measuring bubble point, pore diameter, pore distribution, permeability, and envelope surface area. With suitable attachments, the capability of the porometer can be enhanced for performing tests like liquid permeability, breakthrough pressure, and integrity. The tests can be performed at elevated temperatures, in strong chemical environments, and at high pressures. The sample can be under compressive stress or under cyclic compression. A porometer can also have multiple sample chambers, mobile sample chambers, and sample chambers having many different configurations to accommodate a wide variety of samples. A porometer can also be equipped with suitable test modes for testing high flow samples or low flow samples in quick quality control mode or the more sophisticated investigative mode.
PMI has designed such instruments for many industries including filtration, pharmaceutical, chemical, health care, hygienic, household products, power sources, and paper industries. PMI's Multi-Chamber & Multi-Mode, Permporometers, and Environment Control Porometers are examples of Custom Porometers.
