Gas analysis is the process of measuring and identifying the composition of gases in a given sample. This technique is essential in various fields, including environmental monitoring, industrial processes, and safety assessments. By determining the concentration of different gases, scientists and engineers can evaluate air quality, detect pollutants, and ensure compliance with safety regulations. There are several methods for gas analysis, such as gas chromatography, mass spectrometry, and infrared spectroscopy. Each method has its advantages and is chosen based on the specific requirements of the analysis. Accurate gas analysis helps in understanding chemical reactions, monitoring emissions, and improving overall safety in various applications.
