©2020 Biological and Chemical Oceanography Data Management Office.The Unisense H2S microsensor is a tool for studying H2S production and oxidation in a wide range of applications. The H2S microsensor is a miniaturized amperometric sensor with internal reference and a sensing anode. The anode is polarized against an internal reference. Driven by the external partial pressure, H2S from the environment penetrates through the sensor tip membrane into the electrolyte where the H2S is ultimately oxidized by the anode. This generates a current in the pA range which is measured by a picoammeter. See more on the manufacturer's website: https://www.unisense.com/H2S/

|---|---|---|
| H2S from microsensor profiles of ex situ sediment cores collected in the Chesapeake Bay and measured during 2017-2018 | Unisense A.S. microsensors (Denmark) and motorized micromanipulator system were used for data collection. The 4 channel microsensor multimeter was used, with the following microsensors: Ox-50, pH-200, and H2S-100. Each sensor was used consecutively. | Unisense A.S. microsensors (Denmark) |
