Many scientific tasks—including studying the composition of blood and sequencing DNA—depend on being able to separate the parts from the whole. Only then can a scientist begin to understand how the pieces build up a process. To separate a sample into its components, scientists have been continually improving traditional approaches as well as developing new ones. In some cases, the improvements speed up separations; in others, advanced techniques provide new forms of separation that improve the efficiency of the processes. Though technologies are growing increasingly sophisticated, they are also becoming easier to use.
