-1 contains nitric acid 13–20 % CAS 7697-37-2. DANGER Causes se-
vere skin burns and eye damage. Do not breathe dust / vapors. Wear protective
gloves / eye protection. IF ON SKIN (or hair): Take off immediately all contami-
nated clothing. Rinse skin with water [or shower]. IF IN EYES: Rinse cautiously
with water for several minutes. Remove contact lenses, if present and easy to do.
Continue rinsing. Immediately call a POISON CENTER / doctor.
General indications:
Remove only as many test strips as are required. Close the container immedi-
ately after removing a strip. Do not touch the test fi eld.
Instructions for use:
1. Rinse the measuring vessel with the test solution and fi ll it to the 5 mL mark.
2. Add 5 drops PO
4
3–
-1 (nitric acid) to the sample.
3. Shake carefully.
4. Place the measuring vessel on the benchtop and remove the test tube from
the package
5. Place the test tube into the cavity of the thermoformed mould.
6. Add 6 drops PO
4
3–
-2 to the test tube.
7. Insert the test strip into the sample.
8. Wait 15 seconds.
9. Shake off excess liquid.
10. Place test strip into the fi lled test tube.
11. Wait 15 seconds.
12. Shake off excess liquid.
13. Wait 60 seconds.
14. Compare with the color scale.
If phosphate ions are present, the test fi eld turns blue-green.
Interferences:
This test only detects ortho-phosphate. Other phosphates, such as poly-, pyro-
and metaphosphates have to be broken down from the total phosphate by diges-
tion. Silicic acid (SiO
2
) contents above 10 mg/L reacts in the same way giving a
blue colouration thus simulating a higher phosphate concentration. Larger con-
centrations of sulfi de ions (S
2–
) cause a brown color of the test fi eld, and smaller
concentrations lead to low test results.

Disposal:
The used analysis specimens can be fl ushed down the drain with tap water and
channeled off to the local sewage treatment works. Used test strips can be dis-
posed in household waste.
Storage:
Avoid exposing the strips to sunlight and moisture. Keep container cool and dry
(storage temperature 4–30 °C).
If correctly stored, the test strips may be used until the use-by-date printed on
the packaging.
