Combination induction plasma tube and current concentrator for introducing a sample into a plasma
Patent
·
OSTI ID:5729528
This patent describes an induction plasma tube. It comprises: a substantially cylindrical electrical induction coil having a central longitudinal axis, a tubular enclosure centered approximately coaxially on the axis and located within the coil, and a radiation shield centered approximately coaxially on the axis inside the enclosure; a current concentrator coaxially disposed within the electrical induction coil and having means for inducing a current in close proximity to the axis; and a sample holder disposed substantially on the axis of the electrical induction coil and adjacent the current concentrator effective to heat a sample disposed thereon by induction heating from the current concentrator.
