DVLS Dual Channel Gas Chromatography for Hydrocarbons in Liquefied Petroleum Gas Analysis
The DVLS LPG Analyzer ASTM D2163 GC solution for determining hydrocarbons in liquefied petroleum gases. This sophisticated system delivers unparalleled accuracy and reliability for hydrocarbon in LPG analysis, making it the preferred choice for refineries, petrochemical plants, and quality control laboratories worldwide.
Advanced Dual-Channel Architecture
The analyzer features an innovative dual-channel gas chromatography configuration that sets new standards for hydrocarbon in LPG by GC analysis. One channel utilizes micropacked columns with a Methanizer FID detector specifically designed for CH4, CO, and CO2 determination. The second channel focuses on comprehensive C1-C5 hydrocarbon analysis, providing complete compositional data for liquefied petroleum gases.
This parallel processing approach ensures simultaneous analysis across all channels, dramatically reducing analysis time while maintaining the highest analytical precision required by ASTM D2163 standards.
Standard Compliance
The DVLS LPG Analyzer exceeds industry requirements by conforming to multiple international standards including ASTM D2163, EN27491, UOP373, and UOP603. This multi-standard compliance ensures global acceptance and regulatory compliance across diverse markets and applications.
The system’s adherence to ASTM D2163 specifications enables quantitative determination of individual hydrocarbons in liquefied petroleum gases and propane/propene mixtures, with component concentrations accurately measured.
Innovative Liquefied Gas Injector Technology
At the heart of the system lies the proprietary Liquefied Gas Injector (LGI), a breakthrough technology that revolutionizes sample introduction for hydrocarbons in liquefied petroleum analysis. This closed-system approach eliminates the safety risks and accuracy limitations associated with traditional liquid sampling valves or manual evaporation methods.
The LGI system comprises three key components: the Injector unit, Pressure Station, and Controller. The Injector utilizes proven automotive fuel injection technology, directly introducing liquid samples into the GC inlet with exceptional precision and repeatability.
Superior Analytical Performance
The analyzer delivers exceptional analytical performance with limits of detection at least 10 times lower than ASTM D2163 requirements, with most compounds achieving much better sensitivity. This enhanced sensitivity ensures reliable detection and quantification of trace hydrocarbon impurities that can significantly impact fuel quality and processing efficiency.
Repeatability studies demonstrate outstanding precision.
Advanced Data Processing and Reporting
The system incorporates sophisticated data processing capabilities utilizing theoretical response factors as specified in ASTM D2163. This approach ensures accurate quantification of all detected hydrocarbons while providing normalized volume percentages for comprehensive compositional analysis.
The analyzer’s data acquisition system seamlessly integrates with modern laboratory information management systems, enabling efficient data transfer and regulatory reporting compliance.
Safety and Operational Excellence
Safety remains paramount in the design of the DVLS LPG Analyzer. The closed-system architecture eliminates operator exposure to pressurized liquefied gases while ensuring complete sample integrity throughout the analytical process. The Pressure Station maintains samples in liquid phase, preventing light component volatilization that could compromise analytical accuracy.
