How does a gas chromatograph separate compounds?
A) By their boiling points and polarity
B) By their boiling points
C) By their polarity
D) None of the above
Gas Chromatograph
A gas chromatograph is an analytical instrument used to separate, analyze, and identify compounds in a gaseous sample based on their different boiling points.
Boiling Points
The temperature at which a substance transitions from the liquid phase to the gas phase under standard atmospheric pressure.

Final Answer :
A
Explanation :
Gas chromatography separates compounds based on their boiling points and polarity. The stationary phase is usually a liquid or polymer that interacts differently with the compounds based on their polarity, and the mobile phase is a gas that carries compounds through the column at rates dependent on their boiling points.
