Porous Polymer Columns

Porous polymers are unique, highly retentive stationary phases with a wide applica-

tion range that are able to elute both polar and nonpolar compounds. They are very

hydrophobic, so water has no impact on retention times and even elutes as a good

chromatographic peak. The Q-BOND is our 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 par-

ticle generation. You get reproducible performance from column to column, including

selectivity and flow.
