PONA testing (Paraffins, Olefins, Naphthenes, and Aromatics analysis)—also referred to as Detailed Hydrocarbon Analysis (DHA)—is a critical technique used to determine the precise hydrocarbon composition of petroleum products. PONA testing provides a detailed breakdown of fuel components, helping refiners, blenders, traders, and end users understand fuel quality, performance characteristics, and compliance with specifications. As fuel formulations become more complex and regulatory requirements more stringent, PONA testing plays a vital role in fuel quality control and performance optimisation.

Benefits of PONA Testing / Detailed Hydrocarbon Analysis

• Identifies the detailed hydrocarbon composition of fuels
• Helps evaluate combustion quality, knock tendency, and emissions behaviour
• Supports refinery process control and blending optimisation
• Detects off-spec or contaminated fuels
• Ensures compliance with ASTM, ISO, and industry fuel standards
• Assists in troubleshooting engine and performance issues
