Hi, does anyone know exactly the chemicals in the test tube style water testing kits for Ammonia, Nitrate and Nitrite.

hi,
i dont know the full list of ingredients, but they contain:-
Nitrate-Acetic Acid and Hydrochloric Acid
Nitrite- Acetic Acid, Hydrochloric Acid and something called Ethoxydiglycol
Ammonia-Sodium Hydroxide and Mercury Diiodide

all of these are either Irritants, Corrosive or Toxic

Thanks for that.

I work in a lab and can probably get most of the chemicals, this is why i'm interested in knowing what is them as it would be cheaper for me to get them through work. None of my tests have an ingredients list.

None of my tests have an ingredients list.

I've never seen one with an ingredients list either, I would expect specificaly for this reason. I do have a link somewhere to a comparison of three ammonia test kits which gave some basic info on ingredient, I'll post if I can find it later on.
I'd also be interested to know if you can do it, I think you'll need to be very precise in your calculations and measurements to get an accurate result.

The box usually doesn't carry an ingredients list, but if you go to the companies website you can usually find a MSDS with product composition on it. You should be able to request these over their help line too. Here's API's ammonia test kit MSDS which lists polyethylene glycol and sodium salicylate as the ingredients.
