10.15 Phosphate (PCE-CP 22)
0.00 ... 2.00 mg/l PO
4
Reagent: PCE-CP X0 Tab Kit Phosphate
1. Clean the instrument as described in chapter 2 General information and, if desired or
necessary, perform the ZERO procedure as described in chapter 7.
2. Navigate through the main menu until the parameter PO
3. Fill a 10 ml sample into the cuvette using the dispensing pipette.
4. Then add a bag of Phosphate N°1 powder reagent to the sample and stir it with the
crushing/stirring rod.
5. As soon as the Phosphate N°1 reagent has completely dissolved, add the Phosphate
N°2 reagent to the sample and stir it with the crushing/stirring rod.
6. When the reagents are completely dissolved, place the light protection cover on the
cuvette and press OK
7. As soon as the countdown is completed, you will receive your measurement result.
The pH value of the sample should be between pH 6 and pH 7.
The following components of the sample can falsify the measurement result - if the content is
correspondingly high: chromium >100 mg/l, copper >10 mg/l, iron >100 mg/l, nickel >300 mg/l,
zinc >80 mg/l, silicon dioxide >50 mg/l, silicate >10 mg/l.
The order in which the powder is added must be strictly adhered to.
10.16 Ammonia (PCE-CP 22)
0.00 ... 1.21 mg/l NH
3
Reagents: PCE-CP X0 Tab Ammonia N°1
1. Clean the instrument as described in chapter 2 General information and, if desired or
necessary, perform the ZERO procedure as described in chapter 7.
2. Navigate through the main menu until the parameter NH
3. Fill a 10 ml sample into the cuvette using the dispensing pipette.
4. Then add a tablet of Ammonia N°1 to the sample and crush it with the crushing rod.
5. As soon as the Ammonia N°1 reagent has spread in the sample, add the Ammonia
N°2 reagent to the sample and stir it with the crushing/stirring rod.
6. When the reagents are completely dissolved, place the light protection cover on the
cuvette and press OK
7. As soon as the countdown is completed, you will receive your measurement result.
The order in which the tablets are added must be strictly adhered to.
The Ammonia N°1 tablet only completely dissolves completely after adding Ammonia N°2
tablet.
The temperature of the sample is important for colour development. At temperatures below 20
°C, the reaction time is15 minutes.
