Material Testing
Polymers, metals, alloys, and composites used in a wide range of industries require exacting materials testing to meet specifications for mechanical response and thermal stability. In applications ranging from solar panels to optical assemblies, glasses, thin films, and coatings must be carefully selected to achieve the right optical characteristics. Whatever your application, partnering with a full-suite material testing lab will help you optimize your products from the ground up!
Covalent offers diverse mechanical analysis, thermal testing, electrical probing, and optical characterization methods for materials analysis to help you ensure your parts and products have precisely the right properties and performance.

Capillary Flow Porometry (Porometry)
In Material Property Testing
Capillary Flow Porometry (also called Porometry) is an optimal technique for characterizing through-pore size and size distribution in wettable materials, such as membranes, filtration media, ceramics, and papers. Covalent’s Porometry services use a top-of-line porometer from Anton Paar for maximized flexibility, speed, and reproducibility. See Also: Gas Adsorption Analysis for non-permeable solids

Gas Pycnometry (Pycnometry)
In Material Testing
Gas Pycnometry is one of the most widely used techniques for analyzing true and skeletal density of any solid (even ones which are porous, granular, and irregularly shaped!). It provides fast, high accuracy volume measurements that can be used to calculate density and porosity, and can be adapted to analyze purity, quality, volatile organic content, and stability of certain materials. Covalent uses an industry-leading Ultrapyc 5000 Gas Pycnometer from Anton Paar for true density analysis. This tool achieves best-in-class accuracy across the widest array of sample types, including coatings, polymer foams, cements, mining, pharmaceuticals, ceramics, catalysts, metallurgy and more.

Porosimetry
In Material Testing
Porosimetry (also called "Gas Adsorption" or "Physisorption" Analysis or "BET Analysis") is a highly flexible and accurate technique for measuring specific surface area, pore sizes / size distribution, and overall porosity of solid samples as well as active metal area, dispersion and crystallite size for materials with gas-reactive surface like catalysts. These can impact electrical, physical, and thermal properties and affect overall performance of devices and systems. See also: Capillary Flow Porometry (or Porometry) is an alternative porosity measurement technique suited for permeable samples.
