Q2. What is A GC
Ans. 
A GC stands for Gas Chromatography, a technique used to separate and analyze compounds in a mixture.
• A GC involves injecting a sample into a column where it is vaporized and carried by an inert gas.

• Compounds in the sample interact differently with the column material, causing them to separate based on their properties.

• The separated compounds are detected by a detector and can be identified based on their retention time
