Adsorption Testing

The process by which certain components in the media to be filtered adhere to the filter may affect the composition and concentration of the media to be filtered. Factors such as flow rate, filtration time, concentration of the media to be filtered, preservative concentration, temperature and pH value may affect the adsorption effect. Filter adsorption testing is a process that evaluates the effectiveness of a filter or a filtration system by determining its capacity to adsorb and retain specific types of particles, pollutants, or microorganisms.

The purpose of the adsorption experiment is to examine whether the filter membrane or filter element will take away key components of the medicinal solution, thus affecting the quality of the final product. Filter adsorption testing is vital in the fields of pharmaceuticals, food and beverage production, environmental monitoring, and many more to prevent the spread of diseases and to ensure product safety.

STEMart provides comprehensive and reliable adsorption testing services to ensure that a filter can effectively remove contaminants from water, air, or other fluids.

Standard Tests

• Direct Verification Method

By testing the changes in product composition, concentration, p-state, and preservative concentration before and after filtration, the adsorption capacity of the filter element to the product is judged. Directly verified contact methods can be divided into simulated contact and simulated filling.

• Indirect Verification Method

That is, the filter weighing method. If the product composition and concentration cannot be directly detected, the adsorption capacity of the filter element to the product can be judged by detecting the weight changes of each component of the filter element after contact with the product.
