EN 12916, a European standard, describes a test method for determining the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This standard defines two procedures, A and B:
The polycyclic aromatic hydrocarbon content is determined by summing the di-aromatic and tri+-aromatic hydrocarbons. The total content of aromatic compounds is found by the sum of the individual aromatic hydrocarbon species.
Compounds containing sulfur, nitrogen, and oxygen may interfere with the determination. Mono-alkenes do not mix, but conjugated di-alkenes and, if present, poly-alkenes may interfere with the determination.
Traditionally, aromatic hydrocarbon species are identified on the basis of their specified liquid chromatography column elution (a process of separating one substance from other substances) properties with respect to model aromatic compounds. Their quantification is performed using an external calibration with a single aromatic compound for each, representative or not, of the aromatics present in the sample.
The use of this standard includes hazardous materials, processes and equipment. In this respect, this standard does not purport to address all security problems for use. Therefore, it is the responsibility of employees using this standard to take appropriate measures to ensure the safety and health of employees before the standard is implemented, and to fulfill legal and regulatory requirements for this purpose.
Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, determination of aromatic hydrocarbon species in medium distillates (high performance liquid chromatography method with refractive index detection) within the scope of EN 12916 standard. also provides services.
