Abstract
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.

1-140. (canceled)
A mass spectrometer comprising:
- a torch configured to sustain an ionization source;
- an induction device comprising an aperture for receiving a portion of the torch and configure to provide radio frequency energy into the received torch portion;
- a generator electrically coupled to the induction device and configured to provide power to sustain an inductively coupled plasma in the torch portion received by the induction device, the generator comprising a circuit configured to electrically couple to an induction device and provide power to the induction device in the driven mode to sustain the inductively coupled plasma in the received torch portion in the driven mode and configured to provide power to the induction device in the oscillation mode to sustain the inductively coupled plasma in the received torch portion in the oscillation mode;
- and
- a mass analyzer fluidically coupled to the torch.
