Abstract
(EN)
The present invention provides derivatized indicator compounds, such as pH indicator compounds, which can be covalently immobilized to a variety of solid substrates to produce an indicator pad. Such pads can be used to monitor water quality in variety of settings. In particular, the pads of the invention are useful in devices which monitor the quality of recreational water, such as water in swimming pools, hot tubs, and amusement park attractions, including water slides, and water-based rides. The present invention overcomes the limitations of commercially available pad chemistries.

La présente invention concerne des composés indicateurs dérivatisés, tels que des composés indicateurs de pH, qui peuvent être immobilisés de manière covalente sur divers substrats solides pour produire un tampon indicateur. De tels tampons peuvent être utilisés pour surveiller la qualité de l'eau selon divers réglages. En particulier, les tampons selon l'invention sont utiles dans des dispositifs permettant de surveiller la qualité de l'eau de baignade, telle que l'eau des piscines, des cuves thermales et des attractions de parcs d'attractions, y compris des toboggans aquatiques, et des manèges aquatiques. La présente invention permet de surmonter les problèmes liés à l'utilisation des produits chimiques des tampons disponibles dans le commerce.
