How do you calculate VOC from diesel?

Volatile Organic Compounds (VOCs) from diesel can be calculated by measuring the concentration of specific VOC components in the fuel, such as benzene, toluene, ethylbenzene, and xylene. This is typically done using gas chromatography or similar analytical techniques. The total VOC content can be expressed as a sum of these components, often reported in units such as parts per million (ppm) or milligrams per liter (mg/L). Additionally, regulations may provide specific methods for calculating or estimating VOC emissions from diesel combustion.
