How do scientists separate and identify amino acids, sugars, drugs, and metabolic products in complex biological samples?

Chromatography is one of the most important analytical techniques in modern biology, medicine, biochemistry, and pharmaceutical research. It allows scientists to separate, identify, quantify, and investigate substances that would otherwise be impossible to analyze individually.

This comprehensive high school teaching unit introduces students to chromatography through engaging laboratory applications and real-world examples. From paper chromatography and thin-layer chromatography to high-performance liquid chromatography (HPLC), students develop a deep understanding of analytical science and metabolic physiology.

The resource combines laboratory science, biology, chemistry, data analysis, and biomedical applications into an engaging STEM learning experience.
