What is the mobile phase in gas chromatography?
- A The phase that moves
- B The phase that remains stationary
- C The stationary phase
- D The solvent
That's Correct!
It's Wrong!
In gas chromatography, the mobile phase refers to the phase that moves through the chromatographic column. This phase is typically a carrier gas, such as helium or nitrogen, which carries the sample components through the column. As the mobile phase passes through the stationary phase, the components of the sample are separated based on their interactions with the stationary phase. The mobile phase plays a crucial role in the chromatographic process by facilitating the movement and separation of sample components.
