Flow Sensor for Gas Chromatograph

Hi.
Does anyone know any flow sensor that is calibrated to measure any gas (0-1000sccm)? I need a sensor of this type to be used in gas chromatography to measure H2, N2, He, Ar, Air.

Welcome to the forum.
If by "flow sensor" you mean a flow meter that you plug into a detector for instance to check fuel gas flows then all the GC instrument manufacturers and suppliers provide them. If you want something to plumb into a gas line to check flow then you would need to look at the electronic flow control modules that go with whatever GC you have.

Dear Peter,
I'm not referring just to the flow meter, but the element able to feel the flow as a voltage magnitude, current or resistance and then be converted to a unit of flow. My goal is just this, create a flow meter with this flow sensor.

It sounds as if you are re-inventing the wheel; every GC on the market has these units in them already.
Have you done an internet search at least ?
