Chromatography is important because it is a versatile and small quantities of a material can be separated with ease, it is fast and accurate if the hardware is maintained. Chromatography is one of the most common techniques in analytical technology and needs only a few micrograms of material in order to work.
Chromatography is used to separate different mixtures. It can be used to prepare materials by purifying them, or analyse them. There are many terms used in the process of chromatography; analyte is the term used for the material that needs to be separated in the process, a chromatogram is a visual representation of the output, and eluent is the solvent that the analyte is stored in.
