Find the Right Biodiesel TestFind the biodiesel test right for you... there are many methods of testing biodiesel that you may find useful during the process of making this fuel and after it is finished. For example, it is important to test for a complete reaction and soap content before washing biodiesel (to prevent emulsions). Also, there are several tests to help you conclude whether or not your biodiesel has been completely washed. And finally, there are home tests to determine contaminant levels in your finished fuel, as well as ways to determine cloud and gel points. (Links to these tests in more detail are coming soon!)
27/3 Test - determines if your biodiesel has been fully reacted. Bromophenol Blue Test - calculates the soap content in unwashed fuel.
Clarity Test - check the clarity of the exiting wash water... a good preliminary check. Wash Water pH Test - compare the pH of the exiting wash water to the pH it was when it entered. You can use this information to determine if all the soap has been washed out. Shake Test - to be used with the other two, basically you shake biodiesel with water and see how easily and cleanly they separate. Dirty water is an indication the biodiesel needs more washing.
pHLip Test - This test will let you know if your fuel passes for soap, glycerin, free glycerin, catalyst and oxidation amounts. Clarity Test - determine if there is water present in the finished fuel. Cloud Point Test - find the temperature at which your fuel starts to cloud. Gel Point Test - determine the temperature at which your fuel will begin to gel.
