GC-MS: Varian 450GC - 300 MS/MS


Varian 300 MS/MS

 
• Scan modes: Q1MS, Q3MS, Precursor (Parent), Product(Daughter), Neutral Loss, Selected Ion Monitoring (SIM), Selected Reaction Monitoring (SRM), Full Scan
• Ionization modes: Electron Ionization (EI) or positive/
negative Chemical Ionization (CI)
• Source: EI/CI source with vacuum interlock for quick
change of ion volumes; entrance hexapole isolates
source contaminants from mass filter
• Source temperature: independent control, 20 ºC to
325 ºC
• Filament: single, 50 to 500 μA
• Electron energy: 20 eV, 70 eV or 150 eV
• Mass filters: quadrupole with pre- and post-filters;
lensless design maximizes transmission efficiency
• Collision cell: 180º curved path with pre- and postfilter
region; long path ensures high dissociation
efficiency
• Mass range: up to 800 Da
• Scan rate: up to 6000 Da/sec
• Resolution: 0.7 Da at 1250 Da/sec or 0.6 Da at
500 Da/sec
• EI dynamic range: >10^5 (compound dependent)
• Mass axis stability: ±0.1 Da over 24 hours
• Transfer line temperature: independent control; 50 ºC
to 325 ºC
• Manifold temperature: independent control; 30 ºC to 50 ºC
• Ion detector: positive or negative ions, constant 5 kV
post acceleration voltage
• Carrier gas flow: up to 8 mL
