Universal Solvent Indicating System

A saturation indication system comprising:

• a sorbent body having an upper surface and a lower surface and being configured to absorb a sorbate;
• a film backing being irreversibly bonded to the lower surface of the sorbent body;
• and
• a universal indicating ink formulation partially coated onto the film backing such that the universal indicating ink formulation is disposed between the film backing and the sorbent body, the universal indicating ink formulation including:
• a resin,
• a dye dispersed in the resin, the dye is configured to indicate a state of saturation of the sorbent body,
• wherein the resin and the dye are soluble in a plurality of categories of sorbates consisting of hydrophobic sorbates, hydrophilic sorbates, neutral sorbates, and amphiphilic sorbates.
