  • It is not recommended to conserve the sample for later analysis.

Procedure for O₂ evaluation

In order to evaluate free chlorine concentration in the sample, start program 66 Monochloramine LR. Mix 10mL of sample and 5 drops of Freechlor F Reagent in the sample cell. Add 10mL of sample in the blank cell. Pour Monochlor F Reagent Powder Pillow in each cell. Close cells and shake the cell content for 20 seconds. After 5 minutes, install the pretreated blank cell in the instrument and press ZERO. Remove the blank, insert the prepared sample cell and analyze testing results. The measurement wavelength for spectrophotometers is 655nm. The recommended wavelength for colorimeters is 610nm. See manual for additional information regarding monochloramine and free ammonia nitrogen determination.
