Intertek Allentown’s specialized team performs gas uptake, permeation and immersion testing - sorption analysis - to analyze a range of samples to meet your characterization needs
Intertek Allentown offers customizable sorption analysis to determine the characterization of samples such as polymers, nanoparticles, adsorbents and catalysts. The resulting comprehensive data includes:
In the sorption lab, materials are exposed to gases, vapors, and liquids to measure how much uptake of the adsorbate there is on the adsorbent and how quickly equilibration occurs.
The weight increase or decrease of solid materials can be measured when exposed to gases and vapors. Sorption analysis of this data yields properties such as:
Diffusion information can also be obtained by measuring the rate of weight change.
Specific and unique issues such a determination of porosity and optimization of reactivation conditions for a material can be addressed by the dedicated scientific team in Allentown. They can establish the temperature rise with exposure to a gas stream using liquid and immersion testing, along with determining weight update, solvent resistance, and diffusion & equilibrium coefficients. Liquid and immersion testing is particularly useful for the evaluation of chemical composition.
The Allentown team also has the expertise to answer questions or address any issues you may have regarding sorption within the following industries:
Chemical & Petroleum
How effective is my catalyst and how can I improve its performance?
Will this adsorbent be effective in purifying my gas stream?
Is my material effective for gas storage?
What can I do to improve my catalyst performance?
Is the precious metal in my catalyst well-dispersed and available to catalyze my reaction?
Packaging, Coatings, & Pharmaceuticals
How quickly will gas permeate through a material?
Will a film maintain the freshness of a vegetable?
What can I do to make my coating dry faster?
How much water will my sample pick up, at different relative humidity conditions?
Intertek’s sorption analysis capabilities and expertise provide total quality assurance throughout our customers’ full product lifecycle.
