AbstractPorous glass column packings have been shown to be an effective substrate for gel permeation chromatography. When carbon tetrachloride is used as a solvent in conjuction with infrared detection, the porous glass exhibits adsorptive properties with polystyrene and polyisobutene. A procedure to eliminate these undesirable properties by treatment with hexamethyldisilazane has been developed. Experiments showed complete elution of all injected polymer. The treatment thus permits quantitative fractionation studies using infrared detection.
