Dragon DHA Software Compatible with Clarity® Software

The Data Apex’s chromatography software product Clarity® can now be used with Dragon DHA software. Dragon DHA uses CDF files to process and report detailed hydrocarbon data. Clarity® makes it easy to generate an AIA (*cdf) file by placing a simple check mark in a PostRun form in front of “Export Chromatogram in AIA Format”. After creating the file it can automatically be opened in Dragon DHA software by placing the DragonDHA.exe file path in a “Program to Run” field. […]

ASTM Approves D7900-13: Light Hydrocarbons in Crude Oils

ASTM_D7900ASTM has recently announced a new standard: D7900-13 “Standard Test Method for Determination of Light Hydrocarbons in Stabilized Crude Oils by Gas Chromatography. The standard was developed in a joint effort with the Energy Institute, London and is the technical equivalent of that institute’s IP 601 standard.

D7900-13 stipulates a way to determine the boiling range distribution of hydrocarbons up to nC9. These results can be combined […]

Faster D6730 DHA Using Hydrogen Carrier Gas

ASTM D6730 Detailed Hydrocarbon Analysis (DHA) is a chromatographic method that determines the individual hydrocarbon components of spark-ignition engine fuels. It is often referred to as PONA and/or PIANO analysis. 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 […]

Envantage Dragon MergeIT Improves Crude Oil Characterization

PerkinElmer published an article in Petro Industry News (October/November 2010 edition) highlighting their S-wafer technology in an article titled “Integrating Detailed Hydrocarbon Analysis Data with Simulated Distillation to Improve the Characterisation Of Crude Oils By Gas Chromatography”. In the article Envantage MergeIT software was used to combine SimDis results with DHA results to obtain a more precise characterization of crude oils for an improved boiling point curve.
