Combination induction plasma tube and current concentration for introducing a sample into a plasma
An induction plasma tube is described comprising in combination: a. 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; b. a current concentrator coaxially disposed within the electrical induction coil and having means for inducing a current in close proximity to the axis; and c. 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.
