Connector assembly for an inductively coupled plasma source

摘要

A connector assembly configured to join an induction coil to a radio frequency generator to provide together with a plasma torch, an inductively coupled plasma source for a spectrometer is disclosed. The connector assembly includes a radial clamping member associated with the radio frequency generator and a sealing member. The radial clamping member has an internal surface configured to receive an end of an induction coil. The connector assembly is configured to provide a secure connection between the end of the induction coil and the RF generator that is substantially electrically conductive and substantially liquid-tight without causing lasting deformation of the radial clamping member or the induction coil. An inductively coupled plasma spectrometer comprising such a connector assembly and a method for securing a connection between an induction coil and a radio frequency generator are also disclosed.

1. A connector assembly configured to join an induction coil to a radio frequency generator to provide, together with a plasma torch, an inductively coupled plasma source for a spectrometer, the connector assembly comprising:
a radial clamping member associated with the radio frequency generator, the radial clamping member comprising an internal surface configured to receive an end of an induction coil; and a sealing member, wherein the connector assembly is configured to provide a secure connection between the end of the induction coil and the RF generator that is substantially electrically conductive and substantially liquid-tight without causing lasting deformation of the radial clamping member and wherein the sealing member enables telescopic adjustment of the induction coil position while maintaining the substantially liquid-tight secure connection between the end of the induction coil and the RF generator; and wherein the tightening or fastening of the radial clamping member does not distort or deform the induction coil in any way elastically or plastically.
