Answer 2

Answer:

Concept:

A technique used to divide a sample into its component parts is liquid chromatography. Based on how the sample interacts with the mobile and stationary phases, this separation happens.

Explanation:

According to each component's affinity for the mobile phase, components within a mixture are separated in a column. One component will move through the column more quickly than the other if the components have different polarities and a mobile phase of a certain polarity passes through the column. The chemicals are divided into various bands within the column because molecules of the same drug will typically move in groups. The accompanying bands can be visible if the components being separated are colored. Aside from high-performance liquid chromatography (HPLC), additional instrumental analysis methods, such as UV-VIS spectroscopy1, are used to identify the bands' presence.
