Questions & Step-by-Step Solutions

In gas chromatography, what is the role of the carrier gas?
  • Step 1: Understand that gas chromatography is a technique used to separate different components in a mixture.
  • Step 2: Identify that a carrier gas is a gas that helps move the sample through the chromatography system.
  • Step 3: Realize that the carrier gas creates a flow that transports the sample into the column where separation occurs.
  • Step 4: Note that the choice of carrier gas can affect the efficiency and speed of the separation process.
