HPLC works by pumping a liquid mobile phase through a column containing the stationary phase. The sample mixture is introduced into the mobile phase stream, and as it travels through the column, different components of the mixture interact variably with the stationary phase. This results in different retention times, allowing for the separation of individual components. In catalysis research, HPLC is often utilized to monitor reaction progress, determine the concentration of reactants and products, and study the kinetics of catalytic processes.
