Porometers have transformed the process of measuring membrane porosity rapid and advanced. But as industrial processes advanced, many separations and filtration procedures required automation. Hence, a wide variety of porometers have now flooded the market, each with its unique measurement technique and result.
This can often leave you confused about which porometer to choose for your particular needs. But, don’t fret, this article will compare two porometers that are currently innovating industrial operations as we speak.
The two porometers in comparison are the Cake Forming Porometer and the Complete Filter Cartridge Analyzer. So, without any further delays, let the comparison commence.
Cake Forming Porometer versus Complete Filter Cartridge Analyzer
Unique application
The Cake Forming Porometer is a unique instrument that is, as the name suggests, capable of making cakes from the sample. The pores of samples are categorized based on the structures forming a cake-like shape and those that aren’t cake-like.
A cake can be created under a wide array of testing conditions using this porometer, which is a cost-effective filtration tool that helps the development of appropriate technologies.
Conversely
On the flip side, the Complete Filter Cartridge Analyzer automatically analyzes the perforated geometries of the entire filter cartridge. It’s ideally used in research and development or quality control environments.
This porometer is fast; it’s accurate and non-destructive, which makes it appropriate for any industry where cartridges are used. These can include industries like,
- Pharmaceutical
- Biotechnical
- Detoxification
- Pollution control
- Ceramics
- Automotive
- Filter
- Sintered metal
The specific measurements from this device include foaming point, average pore size, gas pressure, liquid and Frazier permeability, filter integrity, and pore size distribution. All these tests are conducted using a sample chamber, which allows a variety of sample diameters and lengths to be filtered.
Operating principle
The operating principle for the Cake Forming porometer allows spontaneous filling of the sample pores with the wetting liquid. The wetted sample is later treated with gas to displace the liquid from the pores, only to be measured later.
The measurement of gas pressure and the flow rate is done for both the wet and the dry samples for accurate measurement. The gas pressure removes liquid from the pores, which creates cake-like structures.
Comparatively
The Cartridge filter Analyzer starts the process with a wetted sample chamber, which is then sealed. The flow of gas is sent through the filter, which, at some point, will overcome the capillary action and overcome the maximum hole. This point is regarded as the bubble point of the cartridge sample.
Afterward, the pressure is increased, and the flow is measured until all the holes are emptied, and the residue of the sample is dried.
Conclusion,
Both of these machines require minimal operator involvement and can process samples relatively fast. In today’s growing competitive environment, time is money, and porometers are long term investments. For more information visit our site: https://pmiapp.com/
