Ultra High Matrix Introduction
UHMI enables routine analysis of samples containing up to approximately 25% total dissolved solids, substantially extending the matrix tolerance compared with conventional ICP-MS workflows.
ORS4 Collision/Reaction Cell
The fourth-generation ORS4 provides effective removal of polyatomic interferences using helium collision mode with kinetic-energy discrimination.
Cell-gas switching is completed in less than 3 seconds.
Orthogonal Detector System
- Up to 11 orders of dynamic range
- Approximate range 0.1 cps–10 Gcps
- Supports sub-ppt through percent-level concentrations
- Helps minimize over-range measurements.
Agilent G3292A Cooling Unit
The Agilent G3292A is an external recirculating chiller specified for Agilent 7800/7900 ICP-MS systems.
It provides cooling for temperature-sensitive ICP-MS components including the spray-chamber Peltier cooler, interface region, RF system, and work coil.
