Globally, public authorities promote the use of blends of biofuel and conventional fuel through directives and by setting ambitious goals. Standardization bodies, such as ASTM and CEN, have already published methods that outline specifications for biodiesel as blending component and test methods are available to determine the quality of the biodiesel.
All In One Solution: AC Analytical Controls developed an all in one chromatographic solution that complies with all ASTM & EN test methods listed in the biodiesel specifications EN 14214 & ASTM D6751.
