Certified Reference Materials for Detailed Hydrocarbon Analysis (DHA)


The demands for regulatory compliance, optimization of production capacity, quality and productivity is a major subject for laboratory managers and operators.  

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.
