10 mL H2Blue eco formula (non-ethanol solvent) is a reagent which can be used to measure the concentration of dissolved H2 gas (mg/L-ppm) in hydrogen-rich water. When the drops are placed into water containing dissolved molecular hydrogen, the blue drops turn clear. Insure that your H2 Device is Operating at Peak Performance by Monitoring the Level of Dissolved Hydrogen Monthly. Special Feature: Great for Demonstrating the Presence of Dissolved H2 Accurately Test H2 Water in the pH Range of 4 - 10 Comes with a graduated beaker/storage container and stir wand Manufactured in USA *** Helpful hints for measuring: * When measuring H2 water from water ionizers or hydrogen infusion machines, be sure to run the device for at least 20 seconds before taking the 6ml sample. This will insure that you are sampling fresh H2 water, not water which has been sitting in the machine. * The H2Blue spout is designed to dispense a precise droplet size for testing dissolved H2 levels. When dispensing each drop, turn the bottle completely upside down, gently squeeze the bottle until one drop exits the spout, then release the pressure (which creates a small vacuum). Repeat this technique for each drop. Dispensing H2Blue in this way will help to prevent excess reagent from running down the spout. * After completing each measurement, be sure to completely rinse the graduated beaker and stir wand to remove all H2Blue residue. If H2Blue residue is permitted to accumulate on the inside of the graduated beaker or stirring wand, this may result in inaccurate H2 readings. * Because dissolved hydrogen gas starts to escape immediately after the 6mL sample is taken, try to perform measurements as quickly as possible. Multiple drops of H2Blue can be added at once without stirring to save time, but do not add too many, which may cause you to pass the titration endpoint (see picture below). This technique is easier to implement once you know approximately what your dissolved hydrogen levels are. Best results will be obtained when a measurement takes 1 minute or less. Note: You can tell when the end point is approaching by watching how quickly the blue color vanishes with each drop. As you approach the endpoint, the color change will "slow down". * Be sure to use only the beaker supplied with H2Blue (production batches are calibrated using this beaker), and fill the beaker until the bottom of the water's meniscus is at the top of the 6mL graduation mark (see diagram on right). * Fill the graduated beaker directly from the device without using any type of intermediate container (such as a drinking glass or pitcher), and tilt the beaker slightly while filling to minimize any splashing, which could inadvertently force some of the dissolved gas out of the water. * Because dissolved H2 gas is volatile and escapes easily from water, avoid shaking or otherwise agitating the beaker when adding drops, which can significantly reduce the dissolved H2. It is better to "swirl" the sample or use a small straw (provided with each bottle) to gently stir the reagent into the test sample. * When approaching the titration endpoint, be sure to count the last drop which causes the 6mL test sample to remain pale blue. Demonstrating the presence of dissolved H2: In addition to measuring dissolved H2 levels, H2Blue may also be used as a tool to simply "demonstrate the presence" of dissolved hydrogen gas. When used in this way, the user can collect a sample of the water to be tested (e.g an inch or two in a water glass, the amount is not critical), and then add a few drops of H2Blue. The drops will immediately turn clear, demonstrating the presence of dissolved hydrogen gas (H2). Likewise, the same can be done using a sample of any other water to show that it DOES NOT contain dissolved H2. For example, when H2Blue is added to so-called bottled "antioxidant" waters, the drops will not turn clear if the water does not contain dissolved hydrogen gas (plastic and glass bottles cannot hold dissolved hydrogen gas for very long).
