Agilent, G3280-67019, Peristaltic pump assembly, used with series all series 7700 and 8800 ICP-MS systems

Agilent peristaltic pump assembly is a replacement mechanical unit for the sample-introduction pump in compatible Agilent ICP-MS instruments. This configuration is specifically identified for the 7700 and 8800 series. The assembly includes a roller mechanism, tension arms, tension springs, and mounting cover. Together these components help drive liquid through installed peristaltic tubing for routine sample uptake and fluid handling. Mechanical pump wear can affect stable flow, which in turn influences analytical signal stability and rinsing behavior during ICP-MS runs. Replacing the matched assembly during instrument service can restore the original peristaltic mechanism without replacing unrelated nebulizer or interface components. Tubing selection remains dependent on the analytical matrix and installed instrument configuration.
