Graphtrab - GB

This coarse mesh of Graphpac-GB 20/40 mesh is useful for trapping volatile compunds because it has little retention for water, which minimizes interference during desorption. It can be used with thermal or solvent desorption processes.

Spherocarb

Spherocarb is a spherically shaped carbon molecular sieve which has been used in gas chromotography analysis of permanent gases (N2, O2, H2 etc), light hydrocarbons C1-C4 stock gas mixtures (such as N20, S02 and H2S) and other pollution gas mixtures.
