Ph indicator spray
WebbA fluorescent indicator interacts with its environment and goes through changes that affect its fluorescent properties. Greater sensitivity can be achieved by using a fluorescent compound because the detection limits for fluorescence are lower, by a factor of 102 –10 4, than those for colorimetric light absorption. 18. WebbpH tests in turbid and colored solutions. MQuant ® and Reflectoquant ® pH test strips are utilized to measure pH in colored and/or cloudy solutions, where conventional pH-indicator strips can lead to falsified results. In these strips, the pH reaction zone is backed by a transparent carrier film, allowing users to simply evaluate the color from the back side.
