Abstract Vulcan-G, a graphitized carbon black, has been modified with polyethylene glycol 1500 and picric acid for use in analysis of C1–C4 hydrocarbons. By varying the amounts of the modifying agents, the packing material was evaluated in terms of selectivity and retention. Vulcan-G modified with 2.8% PEG 1500 was found to be capable of separating a C1–C4 hydrocarbon mixture in 19 min at 48°. The analysis of 20 light impurities contained in purum-grade 1,3-butadiene was performed at 46° in about 30 min by using Vulcan-G modified with 4.8% picric acid.
