Abstract

A saturation indication system includes a sorbent body with a film backing being irreversibly bonded to the sorbent body. A universal indicating ink formulation is at least partially coated onto the film backing such that the ink formulation is disposed between the film backing and the sorbent body. The universal indicating ink formulation includes a resin and a dye dispersed in the resin. The dye is configured to indicate a state of saturation of the sorbent body, with the resin and the dye being soluble in a plurality of categories of sorbates consisting of hydrophobic sorbates, hydrophilic sorbates, neutral sorbates, and amphiphilic sorbates.
