MEASURING GAS COMPONENTS TOGETHER WITH A PARAMAGNETIC GAS |
摘要 |
The invention concerns a gas analyzer, which comprises: an electromagnet that has an air gap; a power source for supplying cyclically variable electrical current/voltage to said electromagnet; a sample gas conduit and a reference gas conduit opening into said air gap; an exit conduit communicating with said air gap for removing the intermixed sample and reference gases; pressure detecting microphone or microphones connected to said sample gas conduit and to said reference gas conduit for sensing gas pressures at a first acoustic measuring frequency in the respective conduits for giving at least one acoustic pressure signal component; and electronics connected to said microphone(s) to receive said acoustic pressure signal component or components to form at least a first intermediate output signal describing content of a paramagnetic gas component in the sample gas.
