ASTM D5580-compliant aromatic compound analysis system for petrol
Young In's ChroZen ASTM D5580 Player is designed to provide reliable and reproducible quantification of aromatic compounds in petrol, in accordance with the ASTM D5580 reference method. This method is used to evaluate the mass percentage of substances such as benzene, toluene, ethylbenzene, xylenes, trimethylbenzene, and C9 and heavier aromatics. These components, while necessary for improving the octane rating, are also closely monitored for their potential impact on health and the environment. Compliance with this international standard is therefore essential for regulatory compliance in the fuel sector.
The system is based on two chromatographic columns: a TCEP micro-packed pre-column and a non-polar dimethylpolysiloxane column. Two analytical methods are available depending on the compounds targeted: method A for benzene, toluene and 2-hexanone (internal standard), and method B for ethylbenzene, o-xylene, C9+ aromatics and 2-hexanone. The accuracy of the system is supported by careful control of the backflush time, ensuring optimal separation of all analytes, even in complex matrices.
During testing, the system demonstrated excellent repeatability with %RSD ranging from 0.37 to 0.85 over five sequences. The calibration curves show correlation coefficients greater than 0.990, validating the linearity of the measurements in accordance with ASTM specifications. Each analysis is accompanied by a detailed compliance report attesting to the system's performance. The analyser also provides an accurate calculation of the mass percentage using a standardised formula based on the masses of the sample and the internal standard.
The ChroZen ASTM D5580 is an integrated solution that includes the ChroZen GC hardware platform, dedicated chromatographic management software, and the consumables, columns and accessories required for its operation. It is particularly suitable for laboratories specialising in fuel quality control and regulatory environmental analysis.
