Agilent, G3280-67135, ICP-MS Argon Flow Controller

The Agilent ICP-MS argon flow controller is a replacement gas-control assembly for specified inductively coupled plasma mass spectrometers. It supports regulation of the argon supply used by the plasma system, where stable operating conditions are essential for ion production and repeatable elemental measurements. The controller is compatible with Agilent 7700, 7800, 7850, 7900, 8800 and 8900 ICP-MS instrument families. A damaged or malfunctioning flow-control assembly can contribute to unstable plasma behavior or prevent the system from reaching normal operating conditions. Confirm the specific instrument model, service diagnosis and replacement procedure before ordering. Installation involves the instrument's pressurized gas supply and electronic control system, so qualified service personnel should perform the work using the correct isolation and leak-check procedures. After replacement, assess argon flow, plasma ignition, system diagnostics and analytical stability as part of the instrument return-to-service process. The controller is a repair component, not a standalone ICP-MS gas regulator.
