  • Benefits

    • High Quality GC Hardware - All DHA Analyzers are based upon the Agilent GC configured with dedicated columns, injection ports and detectors. 
    • ASTM Compliance - The DHA analyzers comply with the ASTM test methods D5134, D6729, D6730, D6733 and D7900 to determine hydrocarbons and oxygenates in light petroleum streams. 
    • Proven software platform - The analyzers include the PetroReporter software for data processing and reporting of the properties of petroleum streams. PetroReporter is successfully used by a global installed base of leading oil refineries
    • Universal setup - Analyst could also use PetroReporter to process and report data for SimDist, FAME and Gas Calculation applications in addition to DHA. They can use the universal software for various applications
    • High level of Automation - PetroReporter automates the settings per sample type to provide a correct sample identification. User-friendly editors can be used to customize your settings
    • Accurate characterization of crude oils - To improve the boiling point characterization of crude oils the DVLS PetroReporter merges High Temp SimDist with the DHA data. 
    • Application Guarantee - Each analyzer is tested according to the in-house testing procedures to check the system performance and to verify the analyzer specification by a reference sample test. Factory Acceptance Test will be scheduled upon request
  • Configuration

    The DHA configuration is based on the Agilent Gas Chromatograph configured for a test method with the required hardware and software components:

    • Flame Ionization Detector (FID) with high scanning rate
    • Split/Splitless injection port to split the sample for maximum detection and load ability of the column
    • Cryogenic mode (N2 or CO2)
    • 50 or 100 meter DHA analytical column
    • Calibration, reference or quality control samples 
    • PetroReporter software

    DVLS PetroReporter DHAPetroReporter is a universal software tool that automates data processing of petroleum samples. After data processing PetroReporter creates the required DHA reports. Some examples are: Chromatogram plot of the peak labels over a user selectable time interval, Individual hydrocarbons & group types, Oxygenates, PIONA report, TBP distribution, Properties summary of Bromine Number, Gross and Nett Heat of Combustion of liquid, Reid Vapor Pressure, RON and MON values, Specific Gravity.
