A
gas chromatography system for
the Detailed Hydrocarbon Analysis by component and by group, named DHA, is used
to analyze light fractions with final boiling points up to 450°F (225°C).
Samples normally analyzed using this technique are virgin napthas, alkylates,
FCC gasoline, reformates (charge and product), or gases and liquids from the
production of propanes and butanes. Samples containing oxygenated compounds can
also be analyzed with this system.
The DHA analyzer classifies the
electronic signals accumulated by the data acquisition system and uses that
signal to identify individual components present in the sample. Subsequently, it
reports the concentrations of the all of the groups specified by the user:
Paraffins, Isoparaffins, Aromatics, Olefins, Napthens and Oxygenates. If the
system is equipped with a sulfur selective detector, sulfur containing compounds
present in the sample are also identified.
The DHA system, is characterized
by its totally interactive graphics which permit the overlay of chromatograms to
discern even the smallest differences between samples.
The DHA system includes an
Agilent 6890 or 6850 Gas Chromatograph equipped with EPC, autosampler, data
acquisition system, and Hydrocarbon
Expert software; a software specifically designed to bring to the laboratory
the ultra-fast data handling capabilities needed to perform this analysis.
Sample Types:
- Gasoline
- Crude Oil
- Compress Liquid
