Analytics

For many years our analytical labs have been working on the alkoxide-catalyzed transesterification process and the quality characteristics of the target product biodiesel. In addition to production-related analysis, we also examine your raw materials and end products. Based on the results of our analytical tests, you benefit from our consulting competency, for example, through avoiding yield losses or irregularities in the production process.
