Laboratory Report

Introduction

This report presents the results of an analysis conducted on a portable device designed to enrich water with molecular hydrogen — the H2 Nano Premium2, distributed by Hydrogen For Health (Orem, Utah). The device employs electrolysis and pressure to infuse drinking water with dissolved hydrogen (H₂).

Requested tests:

• Concentration of dissolved hydrogen (mg/L) after 5-minute and 10-minute cycles
• Additionally: change in water pH (ΔpH)

Product Description

Name: Hydrogen water enrichment bottle
Model: H2-2R
Batch: N/A
Serial Number: N/A

The bottle is made of single-layer, food-grade polycarbonate with a capacity of 210 mL. Its sealed system allows pressure buildup during electrolysis, enabling dissolved hydrogen concentrations exceeding 1.57 mg/L (the typical maximum at 1 atm). To prevent overpressure, the lid is equipped with a pressure relief valve. The device offers two preset cycles: 5 minutes (activated by a single press of the power button) and 10 minutes (activated by a double press). It features a built-in rechargeable battery and a USB-C charging cable. The display shows both the battery level and the remaining cycle time. A proton exchange membrane (PEM, Nafion®) positioned between two platinum-titanium electrodes allows operation with any type of drinking water, including distilled water, regardless of mineralization.

Materials and Methods

• Water used: distilled; pH 6.29 ± 0.25; temperature 25.1 °C ± 1.5; conductivity 2 µS/cm
• Laboratory elevation: 883 m (0.90 atm); results adjusted to sea level conditions
• Gas chromatograph: SRI 8610C with Hayesep-D 6M column, temperature 80 °C, TCD detector (tungsten-rhenium), carrier gas: nitrogen (99.999%)
• Analysis method: static headspace gas chromatography (HS-GC)
• Calibration: two-point (1.72 and 6.88 mg/L) using a 1000 ppm hydrogen calibration gas

For each test, the bottle was completely filled with distilled water, securely closed, and the desired cycle was initiated (either one or two presses of the power button). After the cycle concluded, the bottle was shaken for 30 seconds, and a 100 mL water sample was collected into a beaker. Immediately, 1000 µL of the sample was drawn using a gas-tight syringe and injected into a headspace vial. The vial was equilibrated for 5 minutes, after which 1000 µL of gas from the headspace was introduced into the gas chromatograph. Each cycle was repeated three times to determine the mean and standard deviation of the H₂ concentration. Based on the mean concentration and the water volume in the bottle, the total available H₂ was calculated. The change in pH (ΔpH) was also measured.
