| Popis: | A solid-state rf generator was evaluated as a source for inductively coupled plasma atomic emission spectrometry (ICP-AES). The generator is controlled by a dedicated computer and is capable of sustaining analytical plasmas at either 27.12 or 40.68 MHz at powers up to 2 kW. The analytical performance of this generator was evaluated with particular emphasis on noise and stability. A quartz chimney was used to reduce audio-frequency noise in the ICP emission. Detection limits for 11 different elements and 22 different emision lines were measured when the ICP was sustained alternatively at each generator frequency. |
