The working principle of high-frequency tungsten-rhenium probe is to use the high temperature generated by high-frequency current passing through tungsten wire for ionization or excitation reaction. When high-frequency current passes through tungsten wire, the tungsten wire will heat up and reach a very high temperature, so that the sample molecules are ionized or excited. Specifically, when the sample molecules come into contact with the high-temperature tungsten wire, thermal dissociation or thermal excitation reaction will occur to generate ions or excited molecules. These ions or excited molecules can be detected and analyzed by subsequent analytical instruments.
