Project Overview
Spot Test Paper - Asia
An Asian company desired entry into the aqueous ion spot-test market and sought help on the chemistry of dyes and suitable substances that would change color when exposed to the species of interest. Information was provided on the chemistry of ion-selective dyes, technology by which these dyes could be incorporated on to the surface of paper and other substrates, and papermaking and finishing into a marketable product.
