March 2, 2007 | AC Analytical Controls® (AC) announces a new brochure on the AC DHA Solutions based on the new Agilent Technologies 7890 gas chromatograph NEW CONFIGURATION
The Detailed Hydrocarbon Analyzers (DHA) use an Agilent Technologies gas chromatograph equipped with:
- A di-methyl silicone capillary column
- A split/splitless (S/SL) injector
- A flame ionization detector
- An automatic liquid sampler
You can select either the new Agilent 7890 GC or the more compact 6850 GC.
FULL RANGE OF APPLICATIONS
The AC DHA applications are dedicated to characterizing the composition of petroleum streams and comply with ASTM methods D 5134, D 6729, D 6730 and D 6733. The AC product range also includes a fast DHA application to determine the individual components in gasoline blending feedstocks within 28 minutes. The DHA Front End (FE) application complies with IP PM-DL to characterize the C1-nC9 fraction in crude oil.
FLEXIBLE DATA SYSTEMS
The DHA applications will offer you flexibility in selecting a gas chromatographic data system.
The DHA Plus software operates on various chromatographic data systems:
* LineUp tool not included
UNIQUE COMBI DESIGN
The AC DHA Combi design allows analysts to combine two DHA applications into one Agilent 7890 GC.
Using the unique AC Combi inlet, the DHA Combi Analyzer includes both the DHA Front End application for light end analysis in crude oil and one of the following standard ASTM test methods:
D 6729, D 6730, D 6733 or the AC Fast DHA application.
