Ammonia HR Kit (PL155-Kit)
Measurement procedure:
1 Prepare 2 Ammonia HR cuvettes (16 mm). Label one as a ZERO cuvette.
2 Open the first cuvette (ZERO cuvette).
3 Fill 0.1 ml distilled water into the cuvette, using a pipette.
4 Open the second vial (sample vial).
5 Fill 0.1 ml sample water in the cuvette.
6 Add 1 x Am. Silic. F5 powder pillow into both cuvettes.
7 Add 1 x Am. Cyan. F5 powder pillow into both cuvettes.
8 Stir with the stirring rod for about 20 seconds until the reagent is completely dissolved.
9 The reagents should now react.
10 Tap TEST to start a 20:00 minute(s) countdown.
11 Place the 16 mm adapter in the PrimeLab.
12 Place the ZERO cuvette in the PrimeLab.
13 Put on the lightshield.
14 Start ZERO measurement.
15 Remove the cuvette again.
16 Insert the sample cuvette in the PrimeLab.
17 Put on the lightshield.
18 Tap TEST to perform the measurement.
Notes:
The test result can be converted into the following unit(s): mg/l NH₃, mg/l NH₄⁺.
Deviations up to 25 % can occur in the low measuring range (0 - 5 mg/l). If you intend to
measure low levels of ammonia, use "ID02 - Ammonia LR".
Adjust strong alkaline or acidic water samples to pH 7 by using 1 mol/l hydrochloric acid or 1
mol/l sodium hydroxide, respectively.
In presence of chlorine, add one drop 0.1 mol/l sodium thiolufate per 0.3 mg/l Cl₂.
