This returns any condensation to the reacted sample. Do not invert the vial right away before inserting into the instrument. It's important to allow time for undissolved particles to settle to The underside and out of The sunshine route with the electronic instrument.
COD contrasts with biochemical oxygen demand (BOD), which relies on using microorganisms to break down the natural and organic substance during the sample by aerobic respiration more than an incubation interval (generally five times).
