Voyager Basics
• Truly portable
– Only 15 pounds (6.8kg) with battery installed
– 15.4” (39cm) long x 10.6” (27cm) wide x 5.9” (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
PHOTOVAC, Inc.
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
PHOTOVAC, Inc.
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

Assay Customization
• Preprogrammed assays can be customized in the
SiteChart software for specific applications
• Existing assays are modified by adding or
deleting compounds
• Full control of all hardware and software methods
development and calibration parameters
• Customized assays are then sent to Voyager from
the PC
