Full Composition Analysis
PAC’s Gas Chromatography systems for Full Composition Analysis are engineered to deliver precise and reliable hydrocarbon composition data across a wide range of applications in the natural gas, LPG, and petrochemical industries. These systems determine the complete component makeup of gaseous and liquefied hydrocarbons, supporting accurate measurements for process control, energy content determination, and product specification verification.
The analytical configuration integrates high-resolution chromatographic columns that ensure excellent separation of components from methane up to C12 hydrocarbons and beyond. This setup provides superior peak definition and baseline stability, resulting in accurate quantification even for trace-level compounds. It supports compliance with ASTM, ISO, and GPA standard test methods for compositional analysis.
Temperature-controlled ovens and precision gas flow management are central to system stability. The GC’s advanced thermal control maintains consistent column temperatures for reproducible retention times and peak shapes, while the carrier gas control ensures steady flow rates, essential for consistent calibration and quantitative analysis. This ensures dependable results under both routine and demanding operating conditions.
Sample introduction is optimized for both gaseous and liquefied hydrocarbons through precision valves and injection systems that prevent fractionation or sample loss. Automated gas sampling valves and vaporizing injectors handle a wide range of sample pressures and concentrations, ensuring representative analysis of complex hydrocarbon streams.
The detection system provides high sensitivity for all measurable hydrocarbon species, allowing full compositional profiling with minimal interference. The detector response is linear across a broad concentration range, supporting both major and minor component quantification without the need for frequent recalibration.
Data acquisition and processing software offers complete automation of the analytical workflow, from method execution to result reporting. The platform includes configurable calibration sequences, integration algorithms, and automated calculation of key physical properties such as relative density, calorific value, and molecular weight based on compositional data.
Engineered for long-term stability and operational robustness, the GC system components are made from corrosion-resistant materials suitable for hydrocarbon service. This ensures consistent performance even in harsh industrial environments, reducing downtime and maintenance requirements while maintaining analytical accuracy.
Through its comprehensive full composition analysis capability, PAC’s Gas Chromatography systems enable laboratories and process facilities to achieve detailed hydrocarbon characterization for quality assurance, process optimization, and regulatory compliance. The system’s analytical precision supports decisions that improve energy measurement accuracy, blending efficiency, and overall process reliability.
