Analytical Chemists require a bachelor's degree in chemistry, physics, or other related field just to obtain entry-level positions. Obtaining extensive lab experience through work-study programs or internships is highly recommended.
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.
