Analytic

For many years our analytical laboratory is engaged in the alkoxide-catalyzed transesterification process and the quality characteristics of the target product biodiesel. In addition to process analysis, we also check your raw materials and final products. On the basis of the analytical investigation, you benefit from our consulting expertise, for example in preventing yield loss or trouble shooting in the production process.
Biodiesel quality check in accordance with EN 14214
