HPLC is applicable to over 80% of all known compounds and is the method of choice over gas chromatography (GC) for the separation of nonvolatile and thermally unstable compounds. In an HPLC system, a pump shoots the mobile phase through the system at the desired flow rate (Fig. 1). Fig. 1. HPLC System Block Diagram

The analysis of caffeine in soft drinks
High performance liquid chromatography (HPLC) is a highly versatile method, which involves the separation of mixtures into their individual components using two phases, solid and liquid, in contact with one another. It consists of five basic parts; solvent pump(s), injector, column (stationary phase), detector, and recorder (computer).

Do this for both the caffeine and acetaminophen. Also, make one solution containing 1.00 x 10-4 g/mL caffeine and 1.00 x 10-4 g/mL of acetaminophen. Theory: Retention in HPLC is strongly dependent upon the composition of the mobile phase and somewhat less dependent upon the composition of the stationary phase.
