Boiling Point Distribution
PAC’s Gas Chromatography systems for Boiling Point Distribution Analysis provide precise hydrocarbon fraction profiling for petroleum products, fuels, and petrochemical streams. These systems accurately determine the boiling point ranges of complex hydrocarbon mixtures, supporting process optimization, product specification verification, and quality control in refining and petrochemical laboratories.
The analytical configuration utilizes high-resolution capillary columns optimized for separating hydrocarbon fractions from light ends to heavy components. This ensures clear peak separation, minimal baseline drift, and reproducible retention times, allowing accurate characterization of boiling point distributions across the entire hydrocarbon range.
Temperature-controlled ovens and advanced thermal programming are critical to reliable analysis. Precise ramping of column temperatures ensures consistent separation of overlapping fractions and maintains reproducibility even for multi-component mixtures, enabling accurate quantification of narrow and broad boiling ranges.
The sample introduction system is designed to handle liquid hydrocarbons with minimal fractionation. Precision injection valves and vaporizing systems ensure representative sample transfer into the GC column, preventing loss of volatile components and ensuring accurate measurement of both light and heavy hydrocarbon fractions.
The detection system delivers high sensitivity and linear response across a wide concentration range, making it suitable for both major and minor hydrocarbon components. Automated integration and quantification routines allow laboratories to rapidly obtain boiling point distributions with high precision and minimal operator intervention.
Data acquisition and software control enable full automation of analysis, from method execution to report generation. The software calculates boiling point ranges, fraction percentages, and cumulative distribution curves, supporting compliance with ASTM and ISO methods, including ASTM D86 and related boiling point characterization standards.
Engineered for reliability and long-term stability, the system components are constructed from corrosion-resistant materials suitable for hydrocarbon analysis. This ensures continuous, maintenance-light operation, ideal for high-throughput laboratories in the petroleum, fuel, and petrochemical industries.
Through precise boiling point distribution analysis, PAC’s GC systems provide laboratories and process facilities with essential insights for quality control, blending optimization, and process monitoring. Accurate fraction profiling enhances product consistency, energy content evaluation, and regulatory compliance.
