AquaSnap® Free measures non-microbial ATP (aka dead cells) in a solution. Use AquaSnap Free in combination with AquaSnap® Total to identify the microbial ATP in a water sample. First, test a sample of water using AquaSnap® Total and record the number (Total load). Then, use AquaSnap® Free on the same sample and record this number (Free ATP). The difference between Total and Free provides an indication of the microbial contamination in the sample.
