Question

In chromatography, ______________ is a developing solution that travels up the stationary phase, carrying the samples with it.

• A. stationary phase
• B. mobile phase
• C. both a and b
• D. none of above

Answer 1

The correct option is B mobile phase

The stationary phase is usually a piece of high quality filter paper.

The mobile phase is a developing solution that travels up the stationary phase, carrying the samples with it.

Components of the sample will separate readily, according to how strongly they adsorb onto the stationary phase versus how readily they dissolve in the mobile phase.

Organic solvents/buffers are used as mobile phase.

Option B is correct.
