Product Overview
Carbon tetrachloride activity (CTC) is the gold standard for measuring gas-phase adsorption capacity. A CTC value of 100% means the carbon can adsorb its own weight in carbon tetrachloride vapor—a demanding test that separates truly high-performance carbons from ordinary grades.
CTC-100 is our benchmark gas-phase carbon, consistently achieving CTC values at or above 100%. This exceptional performance comes from an activation process that maximizes the transport pore network—the meso and macro pores that allow vapor molecules to rapidly access the adsorptive micropores. Without this efficient transport network, even high micropore volume goes underutilized.
