  1. Voyager Gas Chromatograph Concept

  2. 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

  3. 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

  4. 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

  5. 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

  6. Column Scheme: Voyager GC Assay # 1 PID Carrier Gas (N2) Column A 70% Column B ECD 30% Pre-Column Column C Make-Up Carrier Gas Precolumn: 4m x 0.53mm x 2.0 um SPB-35 Column A (HEAVY): 8m x 0.25mm BLANK Fused Silica Column B (MID-RANGE): 20m x 0.32mm x 1.0 um Supelcowax10 (PEG) Column C (LIGHT): 15m x 0.32mm x 12 um Quadrex 007-1

  7. Column Scheme: Voyager GC Assay # 2 - 7 Column A Carrier Gas (N2 or UZ Air) Column B PID Precolumn Column C Precolumn: 2.5m x 0.53mm x 2.0 um SPB-35 Column A (Heavy): 8m x 0.32mm BLANK Fused Silica Column B (Mid-Range): 20m x 0.32mm x 1.5 um Supelcowax 10 (PEG) Column C (Light): 1.2m x 1.6mm 1% SP1000 on 60/80 Carbopack B

  8. Voyager Assays • Target Compounds grouped into Assays (1-7) • Each Assay includes • GC Method • Integration Settings • Compound Library • Assay 1 Environmental Assay • Most comprehensive with 40 compounds • Assay 2-7 Occupational Health and Safety • Targeted by industry segment

  9. Chloromethane Vinyl Chloride Bromomethane Chloroethane Methylene Chloride 1,1-Dichloroethylene Acetone Carbon Disulfide Vinyl Acetate t-1,2-Dichloroethylene Methyl Ethyl Ketone c-1,2-Dichloroethylene Chloroform 1,1,1-Trichloroethane 1,1,2-Trichloroethane Dibromochloromethane Chlorobenzene Ethylbenzene m-Xylene p-Xylene o-Xylene Styrene Bromoform 1,1,2,2-Tetrachloroethane 1,3-Dichlorobenzene 1,4-Dichlorobenzene 1,2-Dichlorobenzene Assay #1 Environmental Compound List Carbon Tetrachloride Benzene 1,2-Dichloroethane Trichloroethylene 2-Chloroethyl Vinyl Ether 1,2-Dichloropropane Bromodichloromethane Methyl Isobutyl Ketone c-1,3-Dichloropropene Toluene t-1,3-Dichloropropene 2-Hexanone Tetrachloroethylene

  10. Assays #2-7: Occupational Health & Safety Assay #2: Petroleum and Petrochemical • Methanol • Ethanol • MTBE • TAME • Benzene • Toluene • Ethylbenzene • m-, o-Xylenes • Naphthalene Assay #6: Surfactant Manufacture • Ethylene Oxide • Propylene Oxide Assay #4: ABS Rubber • Acrylonitrile • 1,3-Butadiene • Styrene • Assay #5: Pulp & Paper • Hydrogen Sulfide • Methyl Mercaptan • Ethyl Mercaptan • Dimethyl Sulfide (DMS) • Dimethyl Disulfide (DMDS) • Acetone • Methyl Ethyl Ketone (MEK) • a-Pinene • Methanol • Assay #7: Latex Paint Monomers • Methyl Acrylate • Methyl Methacrylate • Ethyl Acrylate • n-Butyl Acrylate • iso-Butyl Acrylate • Acrylic Acid • Vinyl Acetate • Ethylene • Styrene

  11. 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
