摘要：Caffeine, preservative and sugar analyses are widely used in food science and analytical chemistry. We have designed a two-stage course-embedded project to determine caffeine and related compounds by high performance liquid chromatography (HPLC) at Georgia Gwinnett College in two analytical chemistry courses (CHEM3000K analytical chemistry and CHEM4100K instrumental chemistry). Built upon our experiences in STEM education, this project is designed to provide our students with more hands-on experience in instrumentation and separation science, to give them better opportunities to enhance their oral and written communication skills, to practice key analytical and chemical separation skills, and to broaden their STEM experience.
