“…Degassing through tubing material has also been reported by McInnes and Kampbell [10], who tested polyethylene and silicon tubing. But in these experiments the loss of H 2 to the atmosphere via the materials used was less than 1 % in 30 min.…”

In this study a field‐sampling technique for dissolved hydrogen (H2) in groundwater will be presented which allows the transport of gaseous samples into the laboratory for further analysis. The method consists of transferring the headspace trapped in a gas‐sampling bulb which is continuously purged by groundwater into previously evacuated vials using a gas‐tight syringe. Three transfer steps with preceding evacuation of the vial led to a H2‐recovery of 100 % in laboratory experiments. The method has been applied to determine H2 concentrations in an aquifer contaminated with chlorinated solvents. Tests concerning the effect of different pumping techniques on H2 concentrations revealed that most reliable values were obtained with a bladder pump, while an electrically driven submersible pump generated considerable amounts of hydrogen due to electrochemical interactions with the sampled water. Concentrations of dissolved hydrogen in field and laboratory samples were about two orders of magnitude higher when sampling was performed with the electrically driven submersible pump compared to sampling with the bladder pump and a peristaltic pump. Lab experiments with a Plexiglas reservoir to produce H2‐enriched water were used to study the effect of two tubing materials (PVC, polyamide) on H2 losses. PVC tubing turned out to allow transfer of H2‐enriched water over 25 m without significant losses, while PA‐tubing was not suitable for sampling of H2.

“…Henry's law is then used to relate the analyte's concentration in the headspace to its concentration in the liquid solution. [18] Bubble strip methods and similar techniques are better suited for one-time measurements because they can be quite timeconsuming. For example, Jiang et al reported that the liquidgas separation process for transformer oil can take up to several days, limiting the effectiveness of early fault detection via the isolation and subsequent analysis of dissolved gases.…”

The former is useful for remediation purposes [18] and the latter for the development of better dietary regimes to increase the quality and quantity of ruminant production.

As hydrogen continues to become rather promising for the generation of clean and sustainable energy, effective and low‐cost sensors are progressively necessary to ensure safety and efficiency of H‐based energy generation processes. Although a wide variety of hydrogen sensors for the gas phase is available, there is still a lack of devices to detect, measure, and track dissolved hydrogen. Determining its concentration is environmentally, economically, and phenomenologically relevant for applications such as offshore transport pipelines, anaerobic generation reactors, and even in electrical transformers. Herein, the technologies for sensing hydrogen dissolved in liquid media are compiled and reviewed, providing a debrief on their operation mechanisms, applications, and features, as well as an outlook of the field to be explored with new functional materials for devices applied on it.

“…Concentrations of CO and molecular H 2 were made using the “bubble strip” method described by Chapelle et al (1996, 1997) and optimized by McInnes and Kampbell (2000). A standard 250‐mL gas sampling bulb (Supelco) was continuously purged with ground water pumped from the well using a peristaltic pump (Geopump) at a rate of approximately 400 mL/min.…”

“…A 20‐mL bubble of nitrogen was introduced into the sampling bulb through the septum. As the bubble was agitated by the stream of inflowing water, slightly soluble gases such as CO and H 2 partitioned from the water into the gas phase and asymptotically approached equilibrium with the water (McInnes and Kampbell 2000). After equilibrium was established (approximately 30 min), an aliquot of gas was withdrawn from the bulb and analyzed for CO and H 2 using gas chromatography with reduction gas detection (Trace Analytical).…”

Dissolved carbon monoxide (CO) is present in ground water produced from a variety of aquifer systems at concentrations ranging from 0.2 to 20 nanomoles per liter (0.0056 to 0.56 microg/L). In two shallow aquifers, one an unconsolidated coastal plain aquifer in Kings Bay, Georgia, and the other a fractured-bedrock aquifer in West Trenton, New Jersey, long-term monitoring showed that CO concentrations varied over time by as much as a factor of 10. Field and laboratory evidence suggests that the delivery of dissolved oxygen to the soil zone and underlying aquifers by periodic recharge events stimulates oxic metabolism and produces transiently high CO concentrations. In between recharge events, the aquifers become anoxic and more substrate limited, CO is consumed as a carbon source, and CO concentrations decrease. According to this model, CO concentrations provide a transient record of oxic metabolism affecting ground water systems after dissolved oxygen has been fully consumed. Because the delivery of oxygen affects the fate and transport of natural and anthropogenic contaminants in ground water, CO concentration changes may be useful for identifying predominantly anoxic ground water systems subject to periodic oxic or microaerophilic conditions.
