Carrier Gas

A carrier gas is a clean, inert gas used in laboratory and scientific instruments, such as chromatography, to transport samples through a system. It acts like a vehicle, carrying substances from one point to another without reacting or interfering with the sample. Common carrier gases include nitrogen, helium, and argon. The choice of gas depends on the specific analytical method and desired separation performance. Overall, the carrier gas ensures that samples move smoothly through the system, allowing for accurate analysis and identification.
