Typical Chromatogram

Key Features and Benefits

  • Approximately a 6 minute analysis time
  • Liquid valves can be added for LPG analysis
  • Can be converted to all capillary columns to achieve better resolution and detection limits
  • A fourth detector can be added for additional capabilities such as analysis of oxygenates, heavy components, trace carbon oxides, or sulfur
