The Agilent G2587-67631 is a service collision-cell assembly intended for the Agilent 6575 Revident LC/Q-TOF mass spectrometer. The collision cell is a key component of the MS/MS ion path between the quadrupole and TOF analyzer. Precursor ions selected by the quadrupole undergo collision-induced dissociation (CID) within the cell, and the resulting product ions are subsequently transferred to the time-of-flight analyzer.

Collision Cell Function
During tandem mass spectrometry, a precursor ion selected by the quadrupole enters the collision cell, where interactions with collision gas produce controlled fragmentation. The resulting product ions are transferred to the TOF analyzer for high-resolution, accurate-mass measurement.
This process supports applications including:
- molecular structure characterization,
- compound identity confirmation,
- product-ion MS/MS spectra,
- unknown screening,
- library matching,
- metabolomics and other omics workflows.
The Revident platform supports acquisition modes including Targeted MS/MS, Directed MS/MS, and Auto MS/MS.
Typical Applications
- Service of Agilent 6575 Revident LC/Q-TOF systems
- Replacement of a damaged collision cell
- LC/Q-TOF refurbishment
- Restoration of MS/MS fragmentation performance
- Preventive or corrective mass spectrometer maintenance
