Gas Chromatographs & GC Mass Spectrometry

The 21st century world is facing a variety of environmental challenge areas both now and in the future. In order to create modern day fuels and lubricants, prevent harmful pollution, and insure regulatory compliance, high precision elemental analysis technology is absolutely essential. SWS is proud to represent manufacturers whose instruments offer client labs a high degree of sensitivity, precision, and accuracy. Present EPA and other agency regulations concerning specifically sulfur content, are approaching historical low levels, thanks to processing technology improvements. SWS will guarantee your application prior to shipment of the instrument.

VUV Analytics


SWS provides an initial educational experience for the client, since the VUV detector is the first of its kind low-UV absorbance detector for GC.  The detector provides value to laboratories through:

  • Orthogonality:  The detector provides comprehensive 3D spectral fingerprints from 120 to 240 nm.
  • Selectivity: Capable of seeing clear spectral differences between isomers
  • Sensitivity:  The VGA-100 is sensitive to the low picogram range for most compounds
  • Linearity:  Between 4 and 7 orders of linearity
  • Simplicity:  With no vacuum pumps and only a light source to maintain the VGA-100 provides the lowest cost of ownership for its capabilities
