Insert Ammonia
Nitrogen
Octa-Slide 2
Bar (3438-01)
into the Octa-
Slide 2 Viewer
(1101).
Match sample color
to color standard.
Record as
Ammonia
Nitrogen.
Fill a test tube
(0106) to the
5 mL line
with the water
sample. Add 4 drops
of Ammonia
Nitrogen
Reagent #1
(4797WT).
Cap and mix.
Insert test tube
into Octa-Slide 2
Viewer (1101).
Add 12 drops
of *Ammonia
Nitrogen
Reagent #2
(4798WT).
Cap and mix.
Wait 1 minute.
Wait 5 minutes.
To express results as Unionized Ammonia
(NH
3
), multiply the test result by 1.2:
Unionized Ammonia (NH
3
) =
ppm Ammonia Nitrogen (NH
3
-N) x 1.2
To express results as Ionized Ammonia (NH
4
+),
multiply the test result by 1.3:
Ionized Ammonia (NH
4
+) =
ppm Ammonia Nitrogen (NH
3
-N) x 1.3
