ABSTRACT:
An adsorption type packing for gas chromatography composed of finely divided carbon particles in whole, and having a ratio of nitrogen gas adsorption at a relative pressure of 0.3 (V.sub.0.3) to nitrogen gas adsorption at a relative pressure of about 1.0 (V.sub.1.0) each in the adsorption isotherm of said packing, V.sub.0.3 /V.sub.1.0, of 0.9 or more and a BET specific surface area of 1,000 to 2,000 m.sup.2 /g; and a process for producing said packing.
