Detailed Hydrocarbon Analyzer (DHA)
Advanced Solution for Hydrocarbon Analysis
Overview
The JAS Detailed Hydrocarbon Analyzer (DHA) is a state-of-the-art system designed to deliver comprehensive hydrocarbon characterization for refinery streams, petrochemical products, and finished fuels. Based on Gas Chromatography (GC) and powered by Hydrocarbon Expert Software, the JAS DHA system provides unparalleled accuracy, speed, and reliability in determining the detailed hydrocarbon composition of complex mixtures.
DHA analysis is essential for quality control, process optimization, and product certification, helping refineries and analytical labs ensure compliance with global fuel specifications and blending requirements.
Method Compatibility
The JAS DHA Analyzer can be configured to comply with a wide range of international standardized methods for gasoline, naphtha, and other petroleum products.
Supported Methods Include:
ASTM D5134, D6729, D6730, D6733, EN ISO 22854, and IP 566.
Each configuration ensures full compliance with method-specific requirements for column setup, calibration standards, and analytical parameters.
System Configuration
The JAS DHA system integrates high-precision GC hardware with optimized inlet, column, and detector configurations for superior performance.
Equipped with advanced FID detection and high-resolution capillary columns, the DHA delivers precise separation and quantification of hundreds of individual hydrocarbon components in a single run.
Every system is factory-configured, fully tested, and ready for plug-and-play operation with Hydrocarbon Expert Software, ensuring seamless data acquisition, processing, and reporting.
