Technology Description:

The Voyager Portable Gas Chromatograph is the smallest instrument of its kind available and weighs just 15 pounds. Voyager is ergonomically contoured and designed to be carried in three ways:

          - Over-the-shoulder harness with a belt harness support to prevent the instrument swinging outwards.

          - On the front of the body using an around-the-neck with belt support harness so that the user can have both hands free to ascend or descend ladders in plant environments.

          - The harness can be totally unclipped from the instrument to allow the user to hand carry the unit using the built-in handle.

          The unique analytical engine incorporates a 3-column arrangement, an advanced design miniaturized photoionization detector (PID), and specially designed miniature stainless steel values for low dead volume and fast contamination-free injections.

          The PID measures contaminants from hundreds of PPM to less than 10 PPB for a variety of Volatile Organic Compounds (VOC) listed in EPA Methods 601, 602, and 624. The Vacuum Ultra Violet (VUV) light source is available in different lamp energies ranging from 8.4 eV to 11.7 eV. The standard lamp energy is 10.6 eV and is applied to a vast range of VOC with ionization potentials less than or equal to this energy.

          A sample molecule absorbs a photon emitted from the VUV light source when the energy of the photon is less than or equal to the ionization potential of the sample molecule. Ions formed are collected in the ionization chamber and the resulting current is proportional to the concentration of the sample compound being ionized.

          The triple capillary column set in the analytical engine comprise a precolumn/backflush configuration with wide-bore capillary columns and are isothermally heated to a maximum temperature of 80 degrees C for reliable compound tracking and identification.

          Samples collected in an internal sample loop or by syringe injection, enter the precolumn. High purity nitrogen is the carrier gas, and the software programs the internal valving to pass through the two columns in series to separate and transfer only those compounds of interest to the analytical column for further separation and detection at the PID. Late-eluting compounds are trapped on the precolumn and backflushed away, thereby significantly reducing analysis time and cost per sample.

          The 3-column set comprises a dedicated column for "lights", "middle", and "heavy" compound classification.

          A valuable "quick screen" function allows TAE sample to be conducted, via the internal pump, directly to the PID to provide measurement of total VOC concentration (in PPM) in a soil, soil gas, or groundwater headspace sample.

          The Voyager GC is a self-contained instrument with built-in carrier tank and a rechargeable battery.
Performance Status/
Limitations:

Limitations:

          The Voyager GC is capable of analyzing compounds with vapor pressures of at least 1mm Hg at 25 degrees C. With the exception of Naphthalene, semi-volatile compounds such as other polyaromatic hydrocarbons, would not be a suitable analytical application of the Voyager GC.

          The Voyageur GC can not be applied to PCB analysis or analysis of CO, CO2, COS, NO2, SO2, SO3, Chlorine, Hydrogen Fluoride, or Nitric Acid and other corrosive vapors.

          By virtue of true (hand-carried) portability, the Voyager GC operates at a maximum isothermal column temperature of 80 degrees C. Liquid samples can not be introduced into the instrument.
