ME3-PH₃ Phosphine Gas Sensor
The ME3-PH₃ phosphine gas sensor is a constant potential electrolytic sensor. Phosphine reacts with oxygen at the working electrode and counter electrode to undergo a redox reaction and release charge to form a current. The magnitude of the current is proportional to the concentration of phosphine. The concentration of phosphine can be determined by measuring the magnitude of the current.
