Weigh sufficient XAD-2 resin (16/50 mesh) to allow preparation of tubes for sampling, blanks, quality control, and recovery studies. (@ 120 mg XAD resin per tube). b. Dissolve sufficient 1-naphthylisothiocyanate in methylene chloride to coat the XAD-2 resin at a 10% loading (w/w). c. Place the XAD-2 resin in the NTIC solution, mix, and remove methylene chloride using rotary evaporation. d. Load the coated XAD-2 resin into 7 cm long, 6-mm OD, 4-mm ID, glass tubes so that the front section contains 80 mg and the back section contains 40 mg. Use PTFE-wool plugs to separate and contain the two sections. Cap the finished tubes with plastic caps.
