A sensitive photoelectric Winkler titrator for respiration measurements

A photoelectric end-point detector for Winkler oxygen titrations is described and has been used to measure respiration rates in unaltered water samples from Chesapeake Bay. The instrument gives a precise measurement of oxygen concentration and permits small changes in concentration to be quantified....

Summary:A photoelectric end-point detector for Winkler oxygen titrations is described and has been used to measure respiration rates in unaltered water samples from Chesapeake Bay. The instrument gives a precise measurement of oxygen concentration and permits small changes in concentration to be quantified. Respiration rates have been measured with incubation periods of 1-6 hours at 13C.
