Qualitative analysis is the process by which a chemist determines what chemical elements are present in a given sample of material. For instance, many people are now concerned about the presence of lead in our environment. Lead is a highly toxic element that can cause both mental and physical problems and, in high doses, even death.

Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration.
