Description
The Clamp-On Porometer is a Capillary Flow Porometer containing a unique mobile sample chamber, which can be attached to the area of the bulk sample to be tested or to the sample that could be made to slide through the chamber. By using this instrument cutting of the samples and damage to the bulk product are eliminated.
Principles of Operation
The location of the material to be tested is fully wetted. The sample chamber is clamped on the material and gas pressure behind the sample is slowly increased to displace the liquid in the pore and increase gas flow. The flow rate of gas is measured as a function of gas pressure. The flow rate versus pressure data are also generated using a dry sample. From these data the characteristics of the pore structure are calculated.
Applications
The Clamp-On Porometer is ideal for testing samples on line and bulk samples without damaging those in any way. The unit is robust and simple to use, and testing is fast and reproducible. Process control is one of the important applications areas for this instrument. Industries world-wide, ranging from the filtration industry to the battery industry, use the PMI Clamp-On Porometer for R&D and quality control. Materials often tested include: filter media, membranes, nonwovens, paper, powders, ceramics and battery separators.
