Abstract: A sensor for hydrogen in a fluid medium has a chamber for electrolyte with a window which is selectively permeable to hydrogen to allow hydrogen to pass from the fluid medium under test into the electrolyte in the chamber. A plurality of electrodes in contact with the ionic liquid electrolyte are used to observe hydrogen concentration by voltammetry. The electrolyte is an ionic liquid. Applications where such a sensor may be used include a wellbore tool for measuring the content of hydrogen in a subterranean fluid, monitoring of fiber-optic cables for damage by hydrogen, corrosion monitoring, and small-scale process plant where hydrogen is part of a gas stream.

Abstract: Generating hydrogen peroxide in situ in a water environment to mitigate biofouling of a water sensor. A hydrogen peroxide generator submerged in the water environment generates hydrogen peroxide to remove/mitigate biofouling of the water sensor. The water sensor may be an electrochemical sensor and the hydrogen peroxide generator may be an electrochemical system that is integrated with the sensor. The water sensor may be able to operate without interference from the generated hydrogen peroxide.

Abstract: A sensor for monitoring a hydrate inhibitor dissolved in a liquid. The sensor includes an internal reflection window for contacting with the liquid. The sensor further includes a mid-infrared light source for directs a beam of mid-infrared radiation into the window to provide for attenuated internal reflection at an interface between the window and the liquid. The internally reflected mid-infrared beam is passed through a narrow bandpass filter which preferentially transmits mid-infrared radiation over a band of wavelengths corresponding to an absorbance peak of the dissolved hydrate inhibitor to filter internally reflected mid-infrared radiation received from the window. The intensity of the reflected mid-infrared beam transmitted through the filter is measured and used to determine an amount of hydrate inhibitor ion the liquid.
