How much time gap between DO fixation and titration is acceptable in case of DO determination by Winkler method ? (In the case of sampling site far from lab causing delay in titration)
In the Winkler method for dissolved oxygen (DO) determination, ideally, the titration should be performed as soon as possible after sample collection and fixation to ensure accurate results. However, if there is a delay due to the sampling site being far from the lab, the samples can still be stable if handled correctly.
Here are some guidelines for acceptable time gaps and precautions:
The time gap between DO fixation and titration should not exceed 2 hours to ensure accurate dissolved oxygen measurements. Delays beyond this period may lead to changes in oxygen levels due to biological or chemical activities.
