The basis of the Winkler procedure is that the oxygen in a sea water sample is made to oxidize iodide ion to iodine quantitatively (in the presence of an alkaline solution of manganese (II) ion); and ...

Dissolved oxygen analyses are performed with an SIO/ODF-designed automated oxygen titrator using photometric end-point detection based on the absorption of 365nm wavelength ultra-violet light. The ...

What is dissolved oxygen (DO)? Why is this parameter so relevant, e.g., for water analysis, and which technologies are used to determine it? In a free White Paper, Dr. Sabrina Gschwind, product ...
