Polar PLOT column, incorporating divinylbenzene ethylene glycol / dimethylacrylate. Highest polarity porous polymer column in Shimadzu PLOT columns. Highly inert for the analysis of polar and nonpolar compounds. Ideal for trace H2S, COS, and mercaptans in hydrocarbon streams. Similar phases: HP-PLOT U, CP-PoraPLOT U, CP-PoraBOND U
