Q: I'm using Cupramine™ and my ammonia test kit is showing ammonia off the scale. What is going on?
A: Ammonia test kits can not distinguish ammonia from the amine based complex present in Cupramine™ and will therefore give a false high reading for ammonia while using Cupramine™. Our Ammonia Alert™ and MultiTest: Free & Total Ammonia™ test kit do not suffer from this problem as they utilize a gas exchange technology that can distinguish ammonia from amines.
