Question

Quizplus · Accepted Answer

Peaks widen with time on column due to diffusion, which refers to the spreading out of a solute molecules as they move through a stationary phase due to random thermal movement. The longer the analyte stays on the column, the more it diffuses, leading to a broader peak. The other options (effusion, adsorption, absorption, viscosity) are not directly related to the widening of peaks on a column chromatography.

The Longer an Analyte Remains on the Column,the Broader the Peak
