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

Fluorogenic sensory polymer strips have been developed to detect and quantify small amounts of water in organic solvents easily, rapidly and inexpensively. The limit of detection 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%.
