Porometer, a participant at FiltXPO 2023 in Chicago, is proudly presenting its cutting-edge products tailored for assessing pore size distribution, as well as gas and liquid permeability.
Leading the way is sales manager Pete Shickel, the face of Porometer at this prestigious event, who passionately shares the company's groundbreaking methodology.
Shickel emphasizes Porometer's utilization of capillary flow porometry (CFP), an innovative technique that quantifies pore size by measuring liquid expulsion. This approach primarily focuses on through pores, which fully traverse solid materials.
Among the standout offerings showcased by Shickel is the POROLUX Cito series, a remarkable range of gas-liquid porometers (GLP). These advanced instruments employ the pressure scan method, a rapid and remarkably consistent approach, to determine pore sizes. Shickel delves into the intricacies of this method, explaining its process of gradually increasing air pressure while simultaneously recording resulting flow rates.
These exceptional instruments deliver comprehensive insights, encompassing crucial parameters such as the first bubble point (representing the largest pore, as per ASTM F-316), mean flow pore size, smallest pore size, pore size distribution, cumulative flow distribution, and gas permeability. Remarkably precise measurements are ensured across the entire pressure range. Shickel elucidates the procedure, stating, "Our exclusive focus is on measuring the spaces or pores that traverse the material. First, the material is saturated with a solution and then carefully placed in the instrument and sealed. The instrument then pressurizes with dry gas, typically nitrogen, exerting pressure on the material. Once the pressure is sufficient to expel the liquid, the instrument precisely calculates the pressure and translates it into pore size using a well-defined equation."
This meticulous approach guarantees remarkably accurate measurements, with the porometers capable of capturing up to 400 real data points, providing unparalleled resolution for characterizing pore sizes in diverse materials.
