What is the purpose of using liquid chromatography in laboratories?

Using liquid chromatography serves a fundamental role in laboratories, primarily aimed at separating mixtures into their individual components for further analysis. This technique is especially beneficial in various fields, such as biochemistry and analytical chemistry, where it is frequently employed for tasks like protein purification and metabolite extraction.

The process allows researchers to isolate specific substances from complex mixtures, enabling detailed study and characterization of each component. For instance, in protein purification, liquid chromatography can effectively separate proteins based on differences in their size, charge, or affinity to specific media, thus aiding in the investigation of their functions and interactions.

The other choices do not align with the primary uses of liquid chromatography. Measuring temperature relates more to thermal analysis techniques, creating reactions under pressure pertains to different synthesis techniques, and synthesizing new compounds typically involves methods like organic synthesis rather than separation methods like chromatography.
