  (15cm) high
• Multiple Column, Dual Detector Portable GC
• 3 Columns (Heavy, Middle, and Light Compounds)
• PID (Photoionization Detector) and optional ECD
  (Electron Capture Detector)
• 3 Levels of Instrument Operation
• Factory programmed methods
• User modified methods
• Total VOC quick screen mode
• Intrinsically Safe (Class 1, Division 1, Groups
  A,B,C D)
• The only portable GC with this classification

Voyager Basics

• Completely self-contained
• Internal carrier gas cylinder
• Oven
• Battery
• Internal data logger
• On-board data handling provides immediate results
  
• No laptop needed in field
• Comprehensive Windows software for data download
  and reports
• Easy to use
• Minimal training required for point press
  operation

Voyager Chromatography

• Carrier Gas
• High Purity Nitrogen or Ultra Zero Air
• Carrier Life 8 hours at 1800 psi
• Carrier Flow Control via Software (Pressure)
• Column Oven
• Isothermal 55oC to 80oC
• Higher temperatures help clean out columns and
  avoid contamination
• Detector Injection Port Heated to Column
  Temperature
• Two Sampling Methods
• Variable Volume Sample Loop
• Syringe Injection

Voyager Chromatography

• Benefits of the 3 column set
• Overlapping selectivities cover
• Heavy compounds (C7 to C12)
• Middle compounds (C3 to C7)
• Light compounds (C1 to C3)
• Simplified method development
• Columns do not degrade
• Vapor phase injections only
• Moderate temperatures with no ramping
