In late 2009 I purchased AquaMetrix. I had a PhD in physical chemistry and worked for years at NASA in molecular spectroscopy. Surely going from spectroscopy to electrochemistry should not be all that hard. So, what if these two fields are as close as a jet fighter is to a bicycle. They’re still categories of physical chemistry, and with the help of the internet and a few trade rags, I would...

Everything discussed in the book so far has dealt with bulk properties of water. The oxidation-reduction potential (ORP) of a solution is the sum of the individual redox values of all species in the water. Likewise, the conductivity is the sum of the individual conductivities of all ionic species. The pH of a solution represents the concentration of H+ ions, but most still think of pH...

This book has covered most of the instrumentation one is likely to find in an industrial or municipal facility that uses or treats water. Except for the optical dissolved oxygen sensor and turbidimeter, electrochemistry has been the foundation of all of them. Electrochemical measurement modalities...

TOC (total organic carbon), BOD, COD, POC, NPOC, DOM, and NOM. Aside from consisting of three letters (with one exception), and with “O” being in the middle, these initials have one thing in common: they measure the amount of organic matter in a sample of water. All organic compounds consist of at least one carbon atom bonded to at least one hydrogen atom. Most consist of multiple C...
