Characterization methods for carbon materials

Norlab offers a whole range of testing instruments for carbon materials.

For powdery carbon materials, the particle size distribution plays a key role for the characterization, while for granulated samples, the meso- and macropores are often the focus of attention.

Investigation of micropores are relevant for both powdery and granulated samples, since the micropores usually exhibit a major part of the specific surface area, and most of the exchange and sorption processes take place there.

For activated carbons, see Characterization methods for MOFs and other synthetic, highly porous materials and Characterization methods for technical adsorbents, including zeolites and activated carbons. Wood, coal, graphite and carbon blacks mostly possess moderate specific surfaces, which are used for other applications.

Specifically carbon blacks, used as fillers for car tires, have led to a special parameter, the so-called STSA surface area, which is measured by gas adsorption and requires a BET analyzer.
