Interferences
5. Swirl to mix. 6. Pipet 1.0 mL of Ferric
Ion Solution into each
sample cell.
7. Swirl to mix. An
orange color will develop
if chloride is present.
8. Touch the timer icon.
Touch
OK.
A two-minute reaction
time will begin.
9. Within five minutes
after the timer beeps,
wipe the blank and place
it into the cell holder.
10. Touch Zero.

Interfering Substance Interference Levels and Treatments
Extreme pH
Should be about pH 2 after adding reagents.
If the sample is strongly acidic or alkaline, adjust a portion of sample before testing to a pH of
about 7. Use either 5.0 N Sodium Hydroxide Standard Solution (Cat. No. 2450-26) or a 1:5
dilution of perchloric acid (Cat. No. 757-65). Use pH paper (Cat. No. 391-33), as most pH
electrodes will contaminate the sample with chloride.
