Detailed Hydrocarbon Analysis (DHA) Certified Reference Materials

Feb 26 2016

In a range of petroleum products, such as crude oils, feedstock, and fuels, detailed hydrocarbon analysis (DHA) is performed to provide crucial information on the molecular composition of the products. The crucial factor for accurate analysis is the calibration, which requires high quality CRM’s.

There are thousands of hydrocarbon compounds, which all have their own molecular and elemental composition. A base DHA analysis supplies the information for over 200 key hydrocarbons present in a wide variety of product matrixes; from crude, through intermediate products to final/end products.

The development of DHA certified reference materials requires adequate experience, as well as suitable chromatography software. The DHA Kit, from DCG Partnership (USA), enables operators to gain crucial information on their products, as well as maintain the highest standard of operation, like accredited ISO 17025 and GUIDE 34 certified reference materials.

Analytical tests related to DHA: ASTM D6729: Individual components in spark ignition fuels by high resolution GC, ASTM D6730: Individual components in spark ignition fuels by pre-column high resolution GC, ASTM D6733: Individual components in spark ignition fuels by capillary high resolution GC, and Other hydrocarbon analysis using GC, GC/MS and ICP/MS techniques.
