Key Features and Benefits

  • Can be configured for both liquid and gas sample analysis.
  • On-board vaporizer converts liquid carbon dioxide to gas phase prior to injection for more repeatable analysis.
  • This application does not analyze ammonia or nitrogen dioxide. Additional applications exist for these components.
