Aims and Objectives of the Experiment
The aim of this experiment is to study the separation of an extract of a non-prescription analgesic tablet containing acetylsalicylic acid (aspirin) and caffeine. The separation is achieved through a well-known process called liquid chromatography. The quantities of the aforementioned substances also need to be determined in the experiment (“High Performance Liquid Chromatography,” n.d.).
Theory and Principles
Chromatography is a technique used for the separation of the components, or solutes, in a mixture. The separation is based on the amounts of the relevant solute in the moving, or fluid, stream. There are two phases in chromatography, the mobile phase, and the stationary ...
