Notes:
Liquid reagents should be stored at temperatures of 5 - 10 °C in securely closed bottles.
Shake the liquid reagent thoroughly before adding the liquid to the vial.
Do not clean glassware and equipment with household detergents, as these could greatly
reduce the measurement result. To prevent any contamination, the cuvette, lid and stirrer
should be stored in a 0.1 % sodium hypochlorite solution for one hour. Then rinse with distilled
water, thoroughly.
If the sample water contains further oxidizing agents, these will react like chlorine and contribute
to the measurement result.
