摘要 |
The present disclosure generally relates to a dye that signals when the concentration of a quaternary ammonium compound in antimicrobial solution changes. A sensor is used to monitor changes in the dye wavelength as an indicator of the quat concentration. The use of a sensor leads to improved precision in measuring quat concentration by eliminating or reducing operator bias in reading color or wavelength changes. The dye can be incorporated into a variety of articles including towels, labels, containers, buckets, trays, sinks, spray bottles, liners for containers, buckets, sinks, or spray bottles, indictor wands or strips, and test kits. |
