The solid phase extraction (SPE) efficiency of 5-methylresorcinol on a variety of cartridges is compared. On the best cartridge found, Bakerpond SDB 1, the SPE characteristics for hydroxybenzene, resorcinol, 5-methylresorcinol and 2,5-dimethylresorcinol are evaluated. Distribution factors and sorption rate factors for these systems are estimated. The effect of NaCl on the SPE efficiency is interpreted.
