Title: Determination of active components of interest in encapsulated and polymers of widespread industrial application Student: Date: Supervisor/s: Laura Garcia Nieto June 2014 Dr. Jacinto Guiteras Departament of Quimica Analitica Otilia Par Vilanova BASF Castellbisbal The TFG was carried out in BASF Castellbisball,a production centre in where more than 300 different products are produced. The quality control laboratory of this centre must quickly identify and quantify quickly some components of interest in the products. Generally, the technique used for the qualitative and quantitative analysis of the components of interest is High Performance Liquid Chromatography (HPLC) This study focuses on four components that are analysed in different types of product: Pyraclostrobin, Vitamin A, DADMAC and acrylamide. These products have particular interest because they are either toxic or active ingredients of the product. A new method for the analysis of Pyraclostrobin and Vitamin A was developed because these are new products for the factory while software for processing the data for DADMAC analysis was programmed. For acrylamide, the objective was to improve the currently established method of analysis because it presented many problems. A method to optimize time in acrylamide analysis was developed.
