Question
**Question:** What is the role of helium gas in gas chromatography? **Options:** - stationary phase - It does not play a role in gas chromatography - mobile phase - analyte **Explanation:** Gas chromatography (GC) is a technique used to separate and analyze compounds that can be vaporized. In GC, the mobile phase is typically an inert gas that carries the sample through the column. Helium is commonly used as this carrier gas due to its inertness, low density, and efficiency in separation processes.
