'''Analytical chemistry''' is a branch of [[chemistry]]. It tries to [[analysis|analyze]] chemicals in things. A simple job would be to see how much [[zinc]] is in a piece of [[brass]]. There are several methods, like [[chromatography]] and [[mass spectrometry]] to do this. [[Flame test]]s can be used for a basic analysis.

More formally: it is the study of the [[chemical]] components of natural and artificial materials.<ref name="isbn0-03-005938-0">{{cite book |author=Holler, F.

[[Qualitative analysis]] finds what [[chemical species]] are in the sample. [[Quantitative analysis]] finds out how much of a substance there are in a sample. Substances in a sample are often separated from each other using [[chromatography]] before the analysis. This is because a sample can contain many different substances.
