brief introduction: RF detector is a key component in communication system and measuring instrument. It is a discharge detector used in gas chromatography.The structure is composed of a metal cylinder and a metal wire in the center of the cylinder.A radio frequency alternating voltage (2 () -4omh:, 2000kV is applied between the cylinder and the wire. The gas in the cylinder (e.g.Carrier gas discharge, so that there is a direct current between the cylinder and the wire through.When the carrier gas flowing through th
