These are preliminary reports that have not been peer-reviewed. They should not be regarded as conclusive, guide clinical practice/health-related behavior, or be reported in news media as established information. For more information, please see our FAQs.
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

Liquid-liquid extraction is a technique of extraction heavily used in chemical industry and especially for purification of pharmaceuticals. Trimetozine was used as a case study to test the performance of an implemented platform capable of conducting the extraction of the analyte of interest from its impurities using a washing solvent. Three stages of pairs of mix-er-settler were designed for a full control of the streams flow rates, the temperature, and the speed of stirring. The countercurrent extraction was chosen with an inline IR sensor as a Process Analytical Technology and a Partial Least Squares model to quantify the partitioning of the different analytes in the downstream of the platform. The dynamics of the extraction was followed experimentally and simulated in MATLAB in order to build black-box model.
