The Agilent 5110 ICP-OES Solid State Radio Frequency (SSRF) generator forms the heart of the
plasma generation system.
The energy produced from the SSRF generator is directed into a suitable gas, in this case argon.
The oscillating electromagnetic field coupled with excitation from a spark igniter causes
ionization of the Argon atoms. The fluctuating electromagnetic field causes further ionization
resulting in collision excitation and ultimately a plasma forming.
The Agilent 5110 Solid State Radio Frequency (SSRF) module is a free running oscillator that
generates a 27MHz sine wave modulated to produce the necessary electromagnetic field.
Available power settings with the SSRF range between 0.7-1.5kW depending on the application.
The SSRF control regulates RF Power to the Coil via the SSRF filter board and RF Oscillator and
communicates with instrument control via a high speed SLIP bus.
