The 5977B Series MSD
The 5977B Series MSD is a stand-alone capillary GC detector.
The MSD features:
• GC Compatibility includes the new Agilent Intuvo 9000 GC, Agilent 7890
Series GC, the Agilent 7820 GC, or the Agilent 6850 MSD
• WEB User Interface (WUI) for locally monitoring and operating the MSD
• A turbo vacuum pump with one of four different foreline pumps
• A diffusion vacuum pump with a Pfeiffer DUO 2.5 foreline pump
• A high efficiency ion source (HES)
• Three different non-HES types of independently heated MSD
electron-ionization (EI) sources available: standard source in both stainless
steel and inert material, and an extractor source.
• Inert ion sources available
• Field upgradeable to chemical ionization (PCI/NCI) modes that add a
chemical-ionization (CI) source, reagent gas flow controller and plumbing,
and CI tuning calibration
• Independently MSD heated hyperbolic quadrupole mass filter
• High-energy dynode (HED) electron multiplier detector
• Independently GC heated GC/MSD interface
• Direct insertion probe (DIP) capability (3rd party).
