Researcher, University of Bristol

Our lab was interested in purchasing a syringe pump from WPI. The company's support was helpful in identifying the required model and even informed us of model-specific limitations (which were of no concern for our intended use). The overall processing and delivery was exceedingly fast – less tha...

About Hydrogen Sulfide

Although hydrogen sulfide is generally thought of in terms of a poisonous gas, it is endogenously produced in many mammalian tissues. It has been detected in micromolar amounts in blood and brain tissue. Hydrogen sulfide is reported as having a broad range of biological functions and although its potential to participate in cell signaling is clear, this biological role is not well understood. Hydrogen sulfide is strongly anagolous to nitric oxide because they share several physical and metabolic properties.

Hydrogen sulfide and oxygen

Like nitric oxide, hydrogen sulfide is a potent vascualr signal that can mediate vasoconstriction or vasorelaxation depending on the oxygen level and tissue. In the rat aorta, hydrogen sulfide concentrations that mediate rapid constriction at oxygen level will cause rapid relaxation at lower oxygen levels.

Sensor details

The ISO-H2S sensor is a low detection limit sensor that works with WPI's Apollo and TBR series of measuring devices to record hydrogen sulfide in vitro. It is the only sensor available that measures hydrogen sulfide.
