GC Columns

SH-Q-BOND PLOT
Non-polar PLOT column incorporating 100% divinylbenzene
Excellent for analysis of C1 to C3 hydrocarbons as well as isomers and alkanes up to C12
High retention for CO2 simplifies gas analysis; CO2 and methane separated from O2/N2/CO. (Note: O2/N2/CO not separated at
ambient temperature.)
Use for analysis of oxygenated compounds and solvents.

SH-U-BOND PLOT
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.
