👉 Analytical fluid, often referred to as a laboratory solvent or reaction medium, is a substance used in chemical analysis and experiments to dissolve and transport solutes through various techniques such as chromatography, spectroscopy, and titration. It serves as a medium that facilitates the separation, identification, and quantification of chemical compounds by providing a uniform environment where interactions between the solute and the solvent can occur efficiently. The choice of analytical fluid depends on the specific analysis required, considering factors like polarity, boiling point, and compatibility with the analytes. Common examples include water, methanol, acetonitrile, and various organic solvents, each chosen for their unique properties to suit particular analytical methods.
