An inductively coupled plasma (ICP) torch is described that includes an injector protector to shield an injector end. A system embodiment includes, but is not limited to, a tubular sample injector configured to receive an aerosolized sample in an interior defined by walls of the tubular sample injector; an injector protector surrounding at least a portion of the tubular sample injector; an inner tube surrounding at least a portion of the injector protector to form a first annular space between the inner tube and the injector protector, the inner tube defining at least one inlet port for introduction of an auxiliary gas into the first annular space; and an outer tube surrounding at least a portion of the inner tube to form a second annular space, the outer tube defining at least one inlet port for introduction of a cooling gas into the second annular space.
