[[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.
