Voyager

Gas Chromatograph

Concept


Voyager basics

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


Voyager basics1

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 softwarefor data download and reports

  • Easy to use

    • Minimal training required for point & press operation


Voyager chromatography

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 chromatography1

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

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
