Intertek Allentown, an ISO 17025 facility, focuses on custom analytical testing. We offer a suite of specialized instrumentation to conduct analyses across various industries including medical device, pharmaceutical and chemical. Our scientists are experts in their fields and experienced in high level problem-solving. As a leading provider of analytical expertise, we provide answers and create solutions.
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.
Gas/Vapor TestingThe 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:
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:
