Book excerpt: Instrumental methods of analysis Instrumental methods of analysis is a branch of analytical chemistry that uses scientific instruments to study chemical systems: • Purpose Instrumental analysis is used to measure the chemical composition, concentration, molecular structure, and atomic structure of matter. It can also be used to identify the products of a chemical reaction. • Techniques Instrumental analysis uses a variety of techniques, including: • Spectroscopy: Investigates the interaction between matter and electromagnetic radiation • Chromatography: Separates mixtures into their individual components • Electrochemical analysis: Measures the electrical potential in chemical species • Applications Instrumental analysis is used in a variety of industries, including: • Quality control of raw materials and finished products • Detection and estimation of impurities in food, drugs, water, and air • Process optimization and control • Research and development • Hybrid techniques Combinations of two or more techniques are also used, such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography–mass spectrometry (LC-MS).
