Precision, performance, and peace of mind.

The success of ethanol-gasoline blends hinges on the purity of ethanol. We address critical issues such as water content, acidity, residue, methanol levels, and potential contaminants, ensuring your finished blend meets specifications with precision.

About Our Ethanol Testing

The ASTM specification that covers fuel ethanol intended to be blended with gasoline is ASTM D4806, and possess fulll testing capabilities. Our customers include ethanol producers, rail terminals, and fuel terminals.

The purity of ethanol going into fuel blending is critically important if the finished blend is going to meet specifications.  The most common issues with blending ethanol are high water content and low pH (acidity).  Other potential issues include non-volatile residue (gum), high methanol content and contamination with sulfates and chlorides.

The following is a list of the common ethanol-related tests that we perform. If you don’t see a test that you’re interested in, please contact us. We are always adding capabilities, willing to set up new methods, and have a large network of labs to collaborate with.
