Key Features and Benefits

  • On-board vaporizer converts liquid to gas phase prior to injection for more repeatable analysis.
  • Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
  • Ultra-high purity fittings and regulators.
  • Specially passivated tubing ensures repeatability and the lowest detection limits.
  • Multiple valve cuts used to remove analytes of interest from the matrix.
