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-100 is a hydrogen sulfide sensor with a 100µm diameter tip. It is designed like the dry microsensors, however, it works like a traditional ISO-H2S-2 2mm sensor. The sensor can be ordered in a variety of lengths from 1–5mm. It incorporates WPI’s proprietary combination electrode technology in which the hydrogen sulfide-sensing element and separate reference electrode are encased within a single shielded sensor design.
The ISO-H2S-2 was the original 2mm H2S sensor, ideal for many applications. The new ISO-H2S-100 can be used in the same way, but offers several advantages:
- Requires no sleeves or filling solutions
- Durable for long-term use, because of its platinum wire construction
- Rapid response time
- Bigger linear range than the ISO-H2S-2 (Range is based on the length of the sensor tip)
