GC-MS: Varian 450GC - 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 C to 325 C
Filament: single, 50 to 500 μA
Electron energy: 20 eV, 70 eV or 150 eV
Mass filters: quadruple with pre- and post-filters; lensless design maximizes transmission efficiency
Collision cell: 180 curved path with pre- and post filter 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 C to 325 C
Manifold temperature: independent control; 30 C to 50 C
Ion detector: positive or negative ions, constant 5 kV post-acceleration voltage
Carrier gas flow: up to 8 mL
