Water I.D. Primelab 2.0, Manual

Page: 220 / 301

25 Press the 10 ml prepared sample liquid in the filter syringe through the filter adapter into a
clean 24 mm cuvette.
26 Add 10 drop(s) of PL Phosphonate 3 into the cuvette.
27 Screw the lid back on the cuvette.
28 Gently swirl the cuvette to mix the liquid well.
29 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
30 Tap TEST to perform the measurement.
31 The measured value for tPO₄³⁻ (Organophosphnates and phosphates as PO₄³⁻) is
immediately displayed.
32 Remove the cuvette from the PrimeLab and set it aside. It is no longer required for this test.
33 Fill 8 ml of distilled water into a clean 24 mm cuvette.
34 Add exactly 2 ml sample water to the same cuvette.
35 Screw the lid back on the cuvette.
36 Swivel the cuvette back and forth for 5 times.
37 Unscrew the lid from the cuvette.
38 Add 10 drop(s) of PL Phosphonate 3 into the cuvette.
39 Add 1 x 0.05 ml PL Phosphonate 4 scoop(s) powder to the sample water in the cuvette.
40 Screw the lid back on the cuvette.
41 Gently swirl the cuvette to mix the liquid well.
42 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
43 Tap TEST to start a 10:00 minute(s) countdown.
44 After the lapse of a 10:00 minute(s) countdown the total result is displayed, divided in tPO₄³⁻ =
"Organophosp Phosphate as PO₄³⁻" ; PO₄³⁻ = "Phosphate as PO₄³⁻" ; PO₄³⁻ org. =
"Organophosphonate as PO₄³⁻".
Notes:
Special accessories required / not included as standard equipment!
The test result can be displayed as PBTC, NTP, HEDPA, EDTMPA, HMDTMPA, DETPMPA,
HPA.
With this procedure ortho-phosphate ions are detected. Other phosphates/phosphonates must
therefore be converted into ortho-phosphates before the test is begun.
The pH value of the sample water should be between 6 and 7.
