Why is gas used in labs?

Gas is commonly used in labs for a variety of purposes, including as a fuel source for heating and combustion, as a reactant in chemical reactions, and as a carrier gas in chromatography. Gases such as nitrogen, argon, and helium are often utilized for their inert properties, helping to create controlled environments for sensitive experiments. Additionally, certain gases are essential for analytical techniques and equipment, enabling precise measurements and observations in research.
