Analyzer Solutions Guide for the Energy and Chemical Industry

Significance of the Topic

The energy and chemical industry relies on accurate, reliable gas analysis to optimize production, ensure product quality and comply with environmental regulations. Gas chromatography (GC) methods are essential for characterizing feedstocks and products ranging from refinery gas and natural gas streams to reformulated fuels, biodiesel and biogas. Timely detection of trace contaminants such as sulfur species, nitrosamines or dissolved gases in transformer oil helps prevent equipment damage, safety risks and costly downtime.

Objectives and Scope

This guide presents a comprehensive portfolio of preconfigured GC and GC/MS Analyzer solutions designed to meet published standards (ASTM, UOP, EN, GPA, ISO, IP) across key industry applications. The aim is to minimize method development time, simplify instrument validation and deliver consistent data for:

• Refinery gas analysis (permanent gases, C1–C6, H2S, COS)
• Natural gas composition and calorific value
• Reformulated gasoline and oxygenate profiling
• Biofuel quality (FAME content, glycerin, methanol)
• LPG composition and trace impurities
• Trace sulfur and nitrosamine detection
• Transformer oil dissolved gas analysis
• Simulated distillation boiling point distributions
• Greenhouse gas monitoring (N2O, CH4, CO2)

Methodology and Instrumentation

Each analyzer integrates specialized hardware and software to fulfill method requirements with minimal configuration. Key elements include:

• Gas chromatographs with capillary and packed columns (PLOT, PoraPLOT, MolSieve, alumina, PONA, wax phases)
• Detectors: Flame Ionization (FID), Thermal Conductivity (TCD), Sulfur Chemiluminescence (SCD), Micro Electron Capture (ECD), Nitrogen Chemiluminescence (NCD), Pulsed Discharge Helium Ionization (PDHID), Flame Photometric (FPD), Mass Spectrometry (MSD)
• Multimode inlets with split/splitless, programmable temperature vaporization, solvent/matrix vent
• Methanizer modules for CO/CO2 conversion to CH4
• Automated sampling: headspace samplers, liquid sampling valves, micro gasifiers, Capillary Flow Technology Deans Switch and Purge Flow Tees
• Preloaded method templates and calculation macros for compliance reporting

Main Results and Discussion

The portfolio delivers validated analyzer configurations for more than 100 applications. Factory checkout confirms typical detection limits, linear ranges and analysis times for each method. For example:

• 3-channel fast refinery gas analysis in under 10 minutes per ASTM D1945/UOP 539
• Natural gas C1–C9 composition and calorific value in 150–240 seconds using Micro GC
• Reformulated fuel oxygenates and aromatics by parallel-channel FID per ASTM D4815/D5580
• Biodiesel FAME profiling to C24 in 35 minutes per EN 14103
• Simulated distillation boiling curves (ASTM D2887, D7213, D6352) in under 6 minutes
• Trace sulfur detection to low ppb via SCD and N-nitrosamines via NCD in under 20 minutes
• Transformer oil dissolved gases by headspace GC/TCD/FID per ASTM D3612-C
• Greenhouse gas monitoring (N2O at 50 ppb, CH4 and CO2 in low ppm to percent range)

Benefits and Practical Applications

Preconfigured analyzers accelerate laboratory startup, reduce method development and training burden, and deliver reproducible results across sites. Applications include:

• Process control in refineries and petrochemical units
• Transmission quality monitoring for natural gas pipelines
• Fuel blending and compliance testing for gasoline and biofuels
• Catalyst feedstock purity checks (ethylene, propylene, monomers)
• Transformer diagnostics via dissolved gas analysis
• Environmental emissions monitoring for greenhouse gases

Future Trends and Possibilities

Emerging directions include integration of real-time, on-line GC sampling in process units, miniaturized field-deployed micro GC systems, tighter coupling with data analytics and machine learning for predictive maintenance, and expanded detector technologies for multiresponse, high-throughput screening. Continuous automation of sampling, calibration and data processing will further improve lab efficiency and data integrity.

Conclusion

Agilent’s factory-configured Analyzer Solutions offer a fast-track approach to achieving method compliance and high data quality in energy and chemical analysis. By delivering optimized instrument configurations, preloaded methods and application-specific checkout, laboratories can focus on validation and operational results rather than lengthy method development.
