Pore Size Distribution of Track Etched Membranes Porometry is ideal for the pore size measurement of track-etched membranes since these materials usually have almost a perfect cylindrical pore structure from one side to the other. Calculated pore number distributions yield numbers close to that of other methods such as electron microscopy. |

Pore Size Measurement of Coated Papers Porometry is the most ideal method for measuring the pore size distribution of sheet materials. Very high-resolution measurements are possible. This application note deals with two coated specialized papers that are very similar. |

Measurement of Air Filter Pore Size The measurement of pore size data for automotive and other air filters with Porometry is very straightforward. These samples were measured with a Porometer 3G. |

Micro-porous Membranes This is the one of the classic applications for Porometry, the method of displacing a wetting fluid from a porous sample by applying an increasing gas pressure to one side. |

Porometer technical detail The WSI POROMETER gas displacement models (3G, 3Gz, micro, macro and nano) monitor the expulsion of a wetting liquid from the pores of a specimen with increasing pressure. This application note gives details of both gas displacement and liquid displacement Porometry. |
