Every day, worldwide, large quantities of crude oil are processed into various mineral oil products such as petrol, kerosene, diesel, heating oil, and lubricating oil. Mineral oil products are generally composed of mostly saturated hydrocarbons, so-called mineral oil hydrocarbons (MOH). During the production as well as the commercial and private use of mineral oil products, water and soil are repeatedly contaminated. Since mineral oil hydrocarbons are difficult to biodegrade, it is very important to control the contamination of environmental samples with MOHs. The analysis of mineral oil hydrocarbons in drinking water, surface water, and waste water is defined by the European standard EN ISO 9377-2, colloquially called H53. GC-2030 with OCI-2030 injector enables efficient H53 measurements as short narrow-bore columns can be combined with a retention gap or a simple on-column liner. With the help of hydrogen as carrier gas chromatogram runtimes can be further reduced, while maintaining the reliability of the results.
