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

• Mid-polarity porous polymer PLOT column, incorporating high 4-vinylpyridine
• Use for the analysis of nonpolar and polar compounds
• Stable to 250 °C
• Porous divinylbenzene homopolymer

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.
