Abstract
Precise concentric alignment of the coolant, plasma and sample gas tubes d in conventional ICPs is an operationally important factor often achieved by fused arrangements which effectively preclude dismountability for maintenance and repair. Spacer rings slip-fitted into the coolant and plasma passages provide support for the concentric arrangement and also permit dismountability. Each ring is slotted to direct coolant and plasma gases and improve their intended functions. One ring spans the plasma tube and has a number of vertically-directed peripheral slots producing a laminar plasma gas flow. The other ring spans the coolant passage and has a pair of threads cut at spaced intervals to spiral the coolant gas and improve its heat transfer function. A separable base member supports the concentric lower ends of the tubes.
