mobile phase
This term is a technical specification used exclusively in the field of analytical chemistry, specifically within chromatography. It describes the dynamic component of a separation system, contrasting with the stationary phase. The term carries a neutral, scientific register and is used to describe the medium that transports the solute across a column or plate.
Because it refers to a specific chemical entity or mixture, it is treated as a countable noun in laboratory settings when discussing different types of solvents or varying compositions used across multiple experiments.
Meanings
Examples
The mobile phase carries the sample through the column.
We need to change the composition of the mobile phase to improve resolution.
A mixture of water and acetonitrile is commonly used as the mobile phase.
The analyte interacts with both the stationary and the mobile phase.
I wonder if a different mobile phase would reduce the retention time.
The pump delivers the mobile phase at a constant flow rate.
Adjust the polarity of the mobile phase to separate these two peaks.
The choice of mobile phase is critical for successful chromatography.
