A fiber drum (55lbs) containing 1,3,6,8-Pyrenetetrasulfonic Acid, Tertrasodium Salt (PTSA), CAS# 59572-10-0. It is recommended to blend FDX-98 dye with water treatment formulation in 1:1,000 weight ratio. The concentration should be controlled at 50-200ppb in recirculation systems for the best monitoring performance.
