AB Curricula related to instrumental analysis aim for competency-based education to promotethe development of teaching strategies that encourage students to successfully tackle theproblem-solving and tasks inherent to their profession. However, this endeavor is constrained bythe complexity of equipment and the lack of time in laboratory classes. The objective of this work isto present an alternative high-performance liquid chromatography (HPLC) practice that adapts thedesired competencies to a shorter and more effective timeframe. It seeks more active participationfrom the student and contextualizes chromatographic analysis within a real-world problem thatencompasses the entire analytical process, from sample to final result. In this scenario, the studentreceives a solid sample of spicy paprika from a supermarket and must report the level of spiciness interms of the total amount of capsaicinoids. To achieve this, they must first apply different experimentalconditions for extracting the analytes of interest (varying temperatures and solvents) and selectingthe most optimal condition. This practice is designed for short sessions, specifically conducted intwo 2.5 h laboratory sessions, and has been implemented in the subject “Advanced Techniques inInstrumental Analysis (ATIA)” in the fourth year of the Degree in Biotechnology at the Universityof Cadiz. The results obtained demonstrated a significant increase in student motivation and animprovement in the acquisition of skills; 100% of the students achieved a grade higher than seven inthe final evaluation of their learning process.
