Residue Detection by UV/Vis

Question:
Does Alconox provide information on cleaner residue detection by UV/Vis?

Answer:
Yes. In The Aqueous Cleaning Handbook, written by the Alconox technical support team, cleaner residue detection methods are given for each Alconox detergent. Citranox and Citrajet residues can be detected with citric acid by UV/Vis. More information can be found on the Alconox website at http://www.alconox.com/static/section_top/gen_cleanval.asp.
