Journal · 02/10 — DPD. Not ORP. Here's why.
Paul Fournier
Competitors measure ORP. Peer-reviewed studies measure DPD. A fundamental difference.
Why ORP is unfit to measure H₂.
ORP (Oxidation-Reduction Potential) measures a difference in electrical potential in mV. Many hydrogenated waters advertise -600 mV ORP and present it as proof of efficacy.
Problem: ORP is not specific to H₂. It integrates all reducing ions (vitamin C, polyphenols, mineral salts, residual dissolved oxygen). A water can show -600 mV ORP with 0 PPB of molecular H₂. That's exactly the trap marketers exploit.
The DPD method (N,N-Diethyl-p-Phenylenediamine) is a direct colorimetric assay of dissolved H₂. The reagent reacts specifically with molecular hydrogen — not with other reducing agents. It's the protocol used in Aoki 2012, Korovljev 2018, Kawamura 2016, etc.
Our ELITE 9K displays 9,000 PPB DPD measured on the Hanna HI-96728 (certified quarterly calibration). If we had allowed ourselves ORP, we could have put 12,000 PPB on the label. We did not.
Each ELITE 9K ships with its DPD kit. Verifiable at home.
“If we had allowed ourselves to lie, we would have put 12,000 PPB ORP on the label. Instead, we measure DPD.”
