Paper Chromatography vs. Column Chromatography: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on May 19, 2024
Paper chromatography separates compounds using a paper strip as the stationary phase, while column chromatography uses a column filled with a solid stationary phase.
Key Differences
Paper chromatography operates on the principle of partition chromatography, where components are separated based on differential partitioning between the mobile and stationary phases. Here, the stationary phase is a special paper. In column chromatography, the separation is based on the differential adsorption of substances to the solid stationary phase within a column.
In paper chromatography, the stationary phase is a strip of chromatography paper, and the mobile phase is a solvent that travels up the paper by capillary action. Column chromatography utilizes a column packed with a solid stationary phase, and the mobile phase is a liquid or gas that passes through the column.
Paper chromatography is commonly used for educational purposes and simple separations, such as identifying components in inks or plant extracts. Column chromatography is more widely used in complex sample purification, such as in pharmaceuticals, biochemistry, and industrial applications.
The resolution in paper chromatography is generally lower compared to column chromatography. Column chromatography provides higher resolution and is more efficient for separating complex mixtures due to better control over the process.
Paper chromatography is suitable for small-scale, less complex analyses. Column chromatography, on the other hand, can be scaled up for larger quantities and is capable of handling more complex separations.
