Laboratory Report


This report summarizes the analysis of the Echo H2 ServerTM hydrogen water machine manufactured by Echo Technologies LLC,
Pleasant Grove, UT, USA. The product was tested for dissolved hydrogen concentration.
Product Description
Echo H2 ServerTM Flow-Through Hydrogen Water Machine, Model # - Echo H2 ServerTM, Serial # HUSG00K90157
Product was received for testing 4/28/2021


Dissolved hydrogen concentration (H2)

Test water: ASTM Type I ultrapure ChemWorld, Salt Lake City, UT, USA; temperature: 25⁰C ± 1.5⁰; ec: 0 us/cm; pH: 6.4
Laboratory elevation: 864 meters (0.91 atm); all measurements adjusted to SATP

Test Equipment: SRI 8610C gas chromatograph, Torrance, CA USA
Column: Hayesep-D 6M packed column temp: 80°C
Detector: Tungsten-Rhenium TCD (5000 mvsec max)
Carrier gas: Nitrogen (99.999%) @20 PSI, 20 mL/min
Calibration: Performed on day of testing using third-party calibration gas
FloJet BW5000 water dispenser system w/ 5 gal bottle reservoir, Xylem Inc., Irvine, CA, USA

GC Test Method: Static headspace analysis

Test Configuration: The Flojet reservoir was filled with ultrapure water and the Flojet siphon tube was connected to the reservoir. The
Flojet output tube (1/4” pvc) was connected to the H2 server’s water input port. A 3’ section of ¼” pvc tubing with an on/off spout was
connected to the H2 server output port and suspended above a sink using a clamp and a laboratory stand to permit collection of output
water. Both the H2 server and Flojet were connected to 110 vac power.

On the day of testing, the GC was permitted to warm up for two hours and then calibrated. For each test, the unit under test was
allowed to run for 1 minute to ensure that only fresh hydrogen water was flowing from the unit. After one minute, a 500 mL beaker was
placed under the water stream and 500 mL of sample water was collected. The faucet was then turned off and a water sample was
immediately taken from a depth of 20 mm using a gas-tight syringe. The sample was injected into the headspace vial and agitated on
an equilibrator device for five minutes to permit the dissolved H2 to equilibrate with the headspace. After equilibration, the headspace
was then sampled using a gas-tight syringe and injected into the gas chromatograph for analysis. Three tests were conducted, results
recorded, and the mean and standard deviation calculated.


Dissolved H2: Mean - 1.53 mg/L (ppm) SD - 0.27
