Abstract
A plasma torch assembly (e.g., for an ICP-MS or ICP-AES instrument) with a retractable injector is disclosed. In implementations, the torch assembly includes an injector that can be extended or retracted relative to an auxiliary gas tube of the torch assembly. The injector can be slidably coupled to a torch body that supports the auxiliary gas tube, such that the injector can be moved forward and backward through a passage of the torch body, causing it to extend/retract relative to the auxiliary gas tube.
