Varian 240 GCMS Ion Trap Mass Spectrometer

The Varian 240-MS, combined with the Varian 450-GC, delivers exceptional performance and flexibility with both MS and GC options.

Mass Analysis
• Mass range: 10-1000 Da in 0.1 Da steps; scan range is time programmable throughout the run
• Resolution: Unit mass resolution
• Scan rate: 5000-10000 Da/s
• Mass axis stability: ±0.1 Da over 72 hr

Scanning Modes

• Time programmable: In all modes during the analytical run
• Full scan
• Selected Ion Storage (SIS): Stores up to six ranges of ions
• MS/MS: Using non-resonant or frequency modulated resonant CID
• MSn scanning also available where n ≤ 10
