Project Funding from EU Financial Resources
Janhubová, Karolína ; Řeháková, Pavla (referee) ; Koleňák, Jiří (advisor)
This bachelor thesis deals with the preparation of the project and its financing options. Nowadays many companies use for their projects grants from the European Union, so this option appears as a viable alternative to finance their own projects. This work contains concepts and procedures that are key to build the project and is also dedicated to the analysis of the current status of a project proposal.

Spectrophotometric determination of chlorhexidine in mouthwash employing Lab-In-Syringe automated ion-pair extraction and back-extraction
Řeháková, Pavla ; Horstkotte, Burkhard (advisor) ; Chocholouš, Petr (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Candidate: Pavla Řeháková Supervisor: Dr. Burkhard Horstkotte, Ph.D., M.Sc. Consultant: doc. PharmDr. Hana Sklenářová, Ph.D. Title of the diploma thesis: Spectrophotometric determination of chlorhexidine in mouthwash employing Lab-In-Syringe automated ion-pair extraction and back-extraction In this work, a magnetic stirring-assisted dispersive liquid-liquid micro-extraction (MSA-DLLME) automated by the Lab-In-Syringe technique is presented. MSA-DLLME is based on mixing the sample and an immiscible solvent by the action of a magnetic stirrer for the dispersion of the solvent into fine droplet to enhance the extraction process. In Lab-In-Syringe, the magnetic stirrer is placed inside a syringe void, which is used as extraction chamber. To allow the use of an extraction solvent lighter than water, the syringe was turned upside down in this work. This method was designed for the determination of chlorhexidine in commercial mouthwash samples. To allow the extraction of chlorhexidine, an ion-pair complex with the reagent methyl orange needed to be formed. After the extraction into an organic solvent, the aqueous solution was exchanged and the analyte was back-extracted into an acidic aqueous acceptor to yield...
