Chemists use the process of chromatography to separate and analyze the different parts of a mixture. Different methods of chromatography use different materials (besides paper) to separate mixtures.

In addition to field work, environmental chemists may conduct laboratory work (e.g., analyzing chemical interactions using chromatography or spectroscopy techniques.) They may also take measurements, ...
