HP-PLOT U Columns 

HP-PLOT U consists of bonded, divinylbenzene/ethylene glycol dimethacrylate coated onto a fused silica capillary. PLOT U  is suitable for analyzing hydrocarbons (natural gas, refinery gas, C1-C7, all C1-C3 isomers except propylene and propane); CO2, methane, air/CO, water; and polar compounds. In comparison to HP-PLOT Q, HP-PLOT U demonstrates greater polarity (RI ethyl acetate 630 vs. 576) and, therefore, different selectivity, better peak shape for some polar compounds like water, and a much lower maximum operating temperature. Consider the HP-PLOT U for your analysis. More...
