Low detection limit sensors to record in vitro. 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.
A dry sensor that works like a 2 mm wet sensor
Response time: ~5 s
Detection limit: <5 nM
Sensitivity: 1 to 4 pA/nM
Hight selectivity and sensitivity to hydrogen sulfide with fast response time
Broad linearity
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. Application like measure biological hydrogen sulfide in vivo or in vitro in tissues or biological media, measure hydrogen sulfide released from drugs and cell culture, cell suspensions, arteries, in vivo applications.
Requires no sleeves or filling solutions. Durable for long-term use, because of its platinum wire construction. Rapid response time. Broad linear range (Range is based on the length of the sensor tip).
Like nitric oxide, hydrogen sulfide is a potent vascular 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.
