Q: What is the main advantage of using gas chromatography for qualitative analysis?

Solution: Gas chromatography provides high resolution and sensitivity, making it an excellent choice for qualitative analysis of volatile compounds.

Steps: 6

Step 1: Understand what gas chromatography is. It is a technique used to separate and analyze compounds that can be vaporized without decomposition.
Step 2: Recognize that qualitative analysis means identifying what substances are present in a sample.
Step 3: Learn that gas chromatography can separate different compounds in a mixture very effectively.
Step 4: Note that it has high resolution, which means it can distinguish between compounds that are very similar.
Step 5: Understand that it also has high sensitivity, allowing it to detect even small amounts of substances.
Step 6: Conclude that these features make gas chromatography a great tool for identifying volatile compounds in a sample.
