Analytical Chemistry
What Is Analytical Chemistry? Analytical chemistry is a branch of chemistry focused on the identification, separation, and quantification of matter . It plays a foundational role in scientific research, quality control, drug development, environmental monitoring, and more. Whether you're measuring the concentration of active ingredients in a pharmaceutical formulation or detecting trace contaminants in water, analytical chemistry provides the tools and methods to obtain accurate, reliable data . Core Principles of Analytical Chemistry Analytical chemistry is built upon several fundamental principles: Precision and Accuracy : The ability to measure consistently and closely to the true value. Sensitivity : The smallest quantity of a substance that can be reliably detected. Selectivity : The ability to differentiate the target analyte from other substances. Linearity : The range over which a method gives proportional responses. Limit of Detection (LOD) and Limit ...
