  • Analyzing system for the detection of reducing and oxidizing gases in a carrier gas with a metal-oxide-semiconductor sensor arrangement
    Patent number: 7356420
    Abstract: Analyzing system for the detection of reducing and oxidizing gases in a carrier gas, wherein the detection means are sensors based on semiconductor-type metal oxides that work in the absence of oxygen. The system includes means for connecting to a chamber which contains the sensors, and moreover in that the processing and control include a system of real-time recognition of the gases, which provides a diagram in which the measurements taken on the carrier gas are situated and identified. The analyzing system permits analysis of the gas in real time.
    Type: Grant
