A Robust, High-Performance Semi-Demountable ICP Torch
The Glass Expansion Semi-Demountable Torch is a direct replacement for the standard quartz torch used on the Agilent Technologies® 7700, 7800, 7900, 8800, and 8900 ICP-MS instruments. It is precision-engineered to provide chemical inertness and a choice of injectors for all sample types without compromising analytical performance, usability, or durability.
- A wide choice of injector IDs and materials makes it suitable for use with all sample types including drinking water, soils, sludges, samples containing HF acid, organic solvents, and for semiconductor applications.
- A tapered injector geometry gives laminar gas flows around the injector tip for the best short-term analytical precision.
- Enables easier, tool-free maintenance with an easy-to-clean demountable injector.
To avoid contamination with the lowest backgrounds, the entire sample path is constructed of high purity materials including the quartz torch body, PFA injector adaptor and choice of alumina, sapphire and quartz injectors.
- Quartz injectors are recommended for organic solvents and non-HF matrices.
- Alumina injectors are corrosion-resistant to all mineral acids including HF and aqua regia. They are also used with less volatile organic solvents, e.g., xylene.
- Sapphire injectors are recommended for silicon, geochemistry, and various HF applications or for ultra-pure applications such as the semiconductor industry.
