Patent ID: 8551401

Claim:
A sample preparation assembly, comprising: a torch configured for use with an inductively coupled plasma spectroscopy instrument, the torch including at least two approximately cylindrical tubes arranged substantially concentrically, the at least two approximately cylindrical tubes including a first outer tube and a second inner tube with a gap formed between the first outer tube and the second inner tube, the first outer tube and the second inner tube each coupled to a mounting element configured for securing in place the first outer tube and the second inner tube; an injector configured for use with the inductively coupled plasma spectroscopy instrument, the injector including an injection nozzle and a spray chamber, an exit of the spray chamber leading to the injection nozzle, the injection nozzle positioned at least substantially within the second inner tube when the spray chamber is positioned adjacent the mounting element of the torch; and a heat sink element, the heat sink element including a securing element, the securing element configured to mate with the mounting element of the torch to mechanically support the heat sink element, at least one of the securing element or the mounting element defining at least one aperture through which an inlet of the spray chamber passes.
