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.
Carrier Gas Role – The carrier gas serves as a mobile phase that transports the sample through the chromatography column, facilitating the separation of components based on their interactions with the stationary phase.
