Chromatography
Chromatography is a common laboratory technique used to separate and analyze different components in mixtures, like testing food ingredients, drug compounds, or environmental samples. Think of it like a highly sophisticated filtering system that helps scientists identify what substances are present in a sample. This technique is widely used in pharmaceutical companies, food safety labs, environmental testing facilities, and research institutions. When you see this term in a resume, it usually indicates the candidate has hands-on experience with laboratory analysis and quality control.
