Agilent, G8020-60805, Quartz injector, tapered, 0.8 mm id, for fully demountable torch

The Agilent tapered quartz injector with a 0.8 mm internal diameter is a replaceable sample-introduction component for fully demountable torches on 5000 Series ICP-OES instruments. The narrow injector geometry is designed for routine work with volatile organic solvents, including gasoline-type samples, where stable plasma introduction and control of solvent load are important. Quartz construction and the tapered profile are specific to this torch configuration, so injector selection should follow the plasma-viewing configuration and solvent application. The injector uses a ball-joint spray-chamber connection and is compatible with the 5100, 5110, 5800, and 5900 ICP-OES instrument families when fitted with the appropriate fully demountable torch. It is an injector replacement, not a complete torch, nebulizer, or spray chamber. Inspect for carbon accumulation, damage, and restricted flow during routine maintenance; replacement is appropriate when cleaning no longer restores consistent performance.
