Solid sensory polymer kit for the easy and rapid determination of the concentration of water in organic solvents and ambient humidity

We have prepared a solid sensory polymer kit to detect and quantify the water in organic solvents, as well as the ambient humidity; these determinations are cheap, easy and rapid with our new material. The limit of detection of water is 7 × 10−4% in acetone, 4 × 10−3% in THF, and 3 × 10−4% in toluene. Additionally, the relative humidity in air can be measured between 20% and 100%.
