Porous polymers are unique, highly retentive stationary phases with a wide application range that are able to elute both polar and nonpolar compounds.

• Nonpolar 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 O₂N₂CO (Note: O₂N₂CO not separated at ambient temperature)
• Use for analysis of oxygenated compounds and solvents
• Maximum temperature of 300 °C
• 100% divinylbenzene

These columns are very hydrophobic, so water has no impact on retention times and even elutes as a good chromatographic peak. The Q-BOND is Restek's most nonpolar and widely used porous polymer column; functional groups can be added to increase polarity (i.e., QS-, S-, and U-BOND). The process used to manufacture porous polymer PLOT columns causes the particles to adhere strongly to the walls of the tubing, so there is virtually no particle generation. You get reproducible performance from column to column, including selectivity and flow.
