Abstract
Certain embodiments described herein are directed to induction devices comprising an oxidation resistant material. In certain examples, the induction device comprises a coil of wire that is produced from the oxidation resistant material. In some examples, the oxidation resistant induction device can be used to sustain an inductively coupled plasma in a torch.
Claims18
A mass spectrometer comprising:
- a torch body configured to sustain an inductively coupled plasma;
- an induction device comprising an oxidation resistant material and configured to provide radio frequency energy to the torch body to sustain the plasma in the torch body, wherein the induction device is configured as a helical induction coil comprising a plurality of coil turns coupled to each other, in which the coil turns comprise an effective amount of the oxidation resistant material to permit the inductively coupled plasma to be sustained in the torch body for at least ten hours without substantial oxidation of the helical induction coil;
- and
- a mass analyzer in fluid communication with the torch body and configured to separate species based on mass-to-charge ratios.
