Spectrometry is a scientific technique used to analyze the interaction between matter and electromagnetic radiation. It involves the measurement of the spectrum of light emitted or absorbed by a substance, which provides information about its chemical composition and properties. Spectrometry is a specialized skill that requires specialized instruments, knowledge of the principles and techniques involved, and interpretation of the results. It is commonly used in fields such as chemistry, physics, biology, and medicine to study and analyze various materials, including gases, liquids, and solids.
