Chemical analysis is a branch of analytical chemistry that focuses on the qualitative and quantitative determination of the chemical composition of substances. This field involves the use of various techniques and methods to identify and quantify the chemical components of a sample, such as spectroscopy, chromatography, and mass spectrometry. Chemical analysis is essential in a wide range of industries, including pharmaceuticals, food and beverage, environmental monitoring, and forensics, to ensure the quality and safety of products and materials. The results of chemical analysis can provide valuable information for research, product development, and regulatory compliance.
