You are correct but with the Ammonia test the instructions are differentRest of the salifert tests you look down not sideways. You sure you're checking it correctly? Maybe you're supposed to set it on there and look from the top.
- Add with 5ml syringe 1 ml of water in the test vial.
- Add 6 drops of NH3-1 (watch out caustic!) and swirl gently for 5 seconds.
- Add 6 drops of NH3-2 (watch out contains Mercury salts, wash hands after use, keep away from food, see additional warning under the heading WARNING). Swirl gently for 5 seconds and allow to-stand for 5 minutes.
- Hold the test vial and look through the side of the test vial. Keep the color chart behind the test vial. Ensure that a white piece of the color chart is behind the liquid layer. The values on the color chart are in mg/L total ammonia (that is NH3 + NH4+).
