Chemical analysis is the process of identifying and quantifying the chemical components of a substance. This can involve various techniques, such as spectroscopy, chromatography, and mass spectrometry, which help scientists determine the composition and structure of materials. It is widely used in fields like pharmaceuticals, environmental science, and food safety to ensure quality and compliance with regulations. There are two main types of chemical analysis: qualitative and quantitative. Qualitative analysis identifies the presence of specific substances, while quantitative analysis measures the amount of those substances. Together, these methods provide essential information for research, product development, and safety assessments in various industries.
