Comparison of infrared biodiesel measurement methods - An overview of ASTM-approved methods and those under consideration
There are several options for measuring the amount of biodie-sel in diesel fuel. Methods EN 14078 and AS'lTvI D7371 are more amenable to laboratory testing although wailing for an off-site laboratory to perform the test can take several hours to several days. For a driver whose truck has just been loaded for a delivery, any wail is too long. Other options for more simplified on-site testing that ...

Comparison of EN 14078 and ASTM D7371 infrared biodiesel methods
Infrared (IR) analysis is the most widely used measurement technology for measuring biodiesel in diesel. Both EN 14078 and ASTM D7371 methods use infrared as the analytical method and more specifically FTIR (Fourier Transform Infrared) spectroscopy. Infrared is a common spectroscopic technique used for quantitative and qualitative analysis. In the biodiesel measurement, the fatty acid methyl ...

Get comparable ASTM/EN data for biodiesel blend while saving time and money
If you need to verity how much biodiesel is in a diesel fuel, sending a sample off to a laboratory can take several days to get an answer. This can add unnecessary delays if a truck has just been loaded for a delivery, but must wait for the lab result. The best solution is to have an on-site test where the fuel is loaded or delivered. The two most widely used analytical methods for measuring the ...

InfraSpec VFA-IR Spectrometer for Biodiesel Blend Measurements
Synopsis: Simple, yet powerful, filter-based IR spectrometers are ideal for compliance to the new ASTM 7861 test method for accurately measuring biodiesel blend ratios. The Wilks InfraSpec analyzer was the instrument used to develop and validate this method and thus is the industry standard for field measurement of FAME (Fatty Acid Methyl Ester) blend percentages. Introduction: Biodiesel is a ...

The impact of blending techniques, feedstock choice, and analytical techniques on biodiesel blend accuracy
The National Renewable Energy Laboratory in Golden, Colorado, USA, conducted a nationwide study released in 2005 that compared the actual content of biodiesel in biodiesel/ petroleum diesel blends vs. the nominal content. Results showed that 36% of the samples were incorrectly labeled. Inaccurately blended biofuels can have a negative impact throughout the supply chain, affecting distributors, ...
