What method can be used to separate particles from a suspension?

Centrifugation is a widely used method to separate particles from a suspension based on their density or size. In this process, the suspension is placed in a centrifuge, which spins the sample at high speeds. The centrifugal force generated causes denser particles to move outward and settle at the bottom of the container, forming a pellet, while less dense components remain in the supernatant liquid above. This method is particularly effective for separating particles with varying densities and sizes in a quick and efficient manner.

While filtration is another common method used to separate solids from liquids, it relies on a porous medium to allow the liquid to pass through while trapping the solid particles. Centrifugation, however, is usually more efficient for separating very fine particles that might pass through a filter.

Evaporation involves removing a solvent from a solution or suspension, leaving behind dissolved solids, but it does not actually separate particles in the same sense as centrifugation. Similarly, condensation primarily refers to the process of changing vapor to liquid and is not applicable for particle separation in a suspension.
