Hybrid generators and methods of using them

摘要

Certain embodiments described herein are directed to generators that can be used to sustain a plasma in a driven mode and in an oscillation mode and optionally in a hybrid mode. In some embodiments, the generator is configured to switch between the two modes during operation. In certain instances, the plasma may be ignited when the generator is in a driven mode and may be used to analyze samples when the generator is in an oscillation mode or driven mode or hybrid mode.
