H2HUBB concentration values come from the documented independent tests for each machine. The 500 mL dose is standardized by multiplying the H2HUBB-measured average concentration by 0.5 L so systems with different reservoir sizes and delivery designs can be compared on the same serving volume. Test methods differ by report; open each H2HUBB test report for the documented protocol.
