Analytical chemists determine the structure, composition, and nature of substances by examining and identifying their various elements or compounds. They also study the relationships and interactions among the parts of compounds.
Chemists analyze substances. They determine what is in a substance, how much of something is in a substance, or both. They analyze solids, liquids, and gases. They may try to find the active compound in a substance found in nature, or they may analyze water to see how much lead is present. Chemists create, or synthesize, new substances.
