WALTHAM, MA, October 14, 2008 — Photovac, Inc., the manufacturer of premium instruments for volatile organic compound analysis in air, soil, and groundwater, is pleased to introduce the Voyager for the detection of sulfur species and VOC’s in Natural Gas Production.

Natural gas companies often have the difficult task of separating and scrubbing the raw oil/gas field product to ensure low sulfur content, and remove extraneous volatile organic compounds (VOCs) before the gas is sent for transport. Natural gas with low sulfur and low VOC content is more commercially desirable as the BTU content is boosted and the gas burns more cleanly. The Voyager portable gas chromatograph from Photovac now offers on-site capability for measuring critical sulfur species to establish the sulfur and VOC content in natural gas, thereby allowing production companies to quickly determine corrective measures for the scrubbing and removal of contamination. Further, the Voyager provides datalogging capability so readings can be stored in the instrument and downloaded to a computer for subsequent analysis and recordkeeping purposes. The Voyager is intrinsically safe for operations in hazardous environments.
