Dragon Detailed Hydrocarbon Analysis Software is an application designed specifically for ease of use in petrochemical laboratories. Dragon DHA© software provides fast and accurate identification of the hydrocarbon components of feedstocks, fuels, and other refined products. Unique to the Dragon DHA© application is the use of the “DHA Dashboard” which provides a view of all analytical results on one screen and recalculation of results in real time. Use of the dashboard as well as a fully graphical user interface allows for exceptionally fast verification of results. Dragon DHA© software is compatible with a full range of chromatography systems including:

  • Agilent ChemStation®DHA Standards (including OpenLAB CDS)
  • Agilent EZChrom® (including OpenLAB CDS)
  • ChromPerfect®
  • Galaxie®
  • Any Chromatography Data System capable of AIA (.CDF) file output

Major Features of Dragon DHA Include:

  • New! ASTM D7900-13 Light Hydrocarbons (IP 601)
  • ASTM Methods D5134, D6729, D6730, D6733, as well as proprietary methods
  • PONA and PIANO analyses
  • Quick database creation
  • Fast Peak identification and Results processing
  • Unknowns tab lists unidentified peaks in order of concentration
  • Unknown indexer takes the user directly to the unknown peak for identification
  • Unique Dashboard feature continuously presents the user with all calculated results; results are instantly recalculated when changes are made
  • Hydrocarbon group-type filtering
  • Full preview/printing of reports (Custom report section selection in development)
  • Results are ‘bound’ with the chromatographic data for instant retrieval/archiving
  • Original files and data are never affected (CFR Part 11/ISO 17025)
  • Result files are saved as CDF (AIA) format files and can be accessed by any third-party application that supports reading the AIA file format
  • Result files themselves work as fully functional reference databases
  • Full reports are stored with results for easy retrieval without reprocessing

News You Can Use – Switch to Hydrogen Carrier Gas:

The official ASTM D6730 Method specifies the use of Helium as the carrier gas.  In recent years Helium has become less available, and, as a consequence, more expensive. Switching to the use of Hydrogen as a carrier gas is not only more economical but its chemical properties affect linear velocities in a way that results in the added benefit of shorter analysis run times.

We have posted an article on our blog that was originally written in 2000 by our good friend Neil Johansen. Neil was instrumental in developing the ASTM DHA Methods that we utilize today. In 2000 he took it upon himself to implement hydrogen as the carrier gas and work out the operating conditions necessary to match the DHA component separations obtained using Helium. We have reprinted the entire article on our blog complete with instrument operating conditions and chromatograms. A pdf of the entire article is available for download.
