Analytical Chemistry

Analytical chemistry is the branch of chemistry focused on the identification, separation, and quantification of chemical components in natural and artificial materials. It fundamentally addresses two key questions: "What is present?" (qualitative analysis) and "How much is present?" (quantitative analysis). To answer these, analytical chemists develop and apply a vast array of methods, instrumentation, and statistical techniques, making it a cornerstone for quality control, environmental monitoring, medical diagnostics, and forensic science by providing the essential tools to measure the chemical world.
