So far it wasn’t possible to trace a course precisely during the extraction of natural substances and their partial cleaning in overcritical CO2  afterwards. But in order to be able to control the process and in order to stay energy efficiently and cost effective it is necessary to have an overview of the courses. Within the scope of a Technology Transfer Project  a mobile and ready-for-the-market module that allows NIR-Inline-Monitoring from extractions as well as from reactions in CO2 to 180°C and in 1000 bar was developed between KIT and SITEC company.
