Radio frequency generator. A device used to generate plasma torches in inductively coupled plasma atomic emission spectrometry/mass spectrometry, etc. It generates a high-frequency current that is fed to the inductor coil to excite the argon gas in the quartz torch tube (placed in the coil), forming a plasma torch.
There are two types of self – excited and other – excited (crystal – controlled) oscillators. The oscillation frequency is 3 ~ 50MHz, usually 27.12MHz and 40.68MHz, and the output power is 0.7 ~ 7kW, usually 1.0 ~ 2.0kW.
There are two main types of high-frequency generators:
(1) “self-excited” generator (self-excited oscillation of electronic tube). It can make the frequency of the oscillating current vary with the impedance of the plasma. Self-excited oscillator circuit is simple, oscillation, excitation, power amplification are completed by a tube at the same time, easy to match the load impedance, easy to ignite the plasma, but the frequency stability is slightly poor.
(2) “it excited” type quartz frequency stabilizer generator (crystal controlled oscillation). It is the use of piezoelectric crystal oscillation to adjust the current frequency, so as to keep the frequency constant. The main advantages of this generator are constant oscillation frequency, stable power, high conversion efficiency and strong anti-interference ability. Its structure is more complex than the “self-excited” generator, but its application in ICP commercial instruments is more extensive than the self-excited oscillator.
The oscillator is composed of crystal oscillation, frequency doubling, excitation, power amplification and other parts. It has high frequency stability, but the matching requirement of output impedance is more strict. It is also equipped with impedance matching network and directional coupler for stable output power. Generally, the high frequency generator is required to have stable power output, no electrical interference to the measuring system, high power conversion efficiency and frequency stability as far as possible.
