Chromatography basics

The attraction of one substance to the surface of another is defined as:

• absorption

• adsorption

• desorption

• intermolecular attraction

The chemical that is of interest in a chemical analysis is known as the:

• analyte

• eluent

• precipitating agent

• reagent

A graph of data that involves two variables; it is used to determine the value of one of the variables. A graph of this type is known as a ...curve.

The output of a chromatography procedure is known as a:

• calibration curve

• chromatograph

• chromatogram

• spectrum

A technique for separating the components of a mixture using a mobile phase and a stationary phase.

• chromatography

• filtration

• gravimetric analysis

• titration

What is a chromatographic technique that uses a column for the stationary phase and a liquid for the mobile phase? Write the answer.

The breaking ofthe attraction between a substance and a surface is known as ...

The solvent that carries the components that pass through a chromatography column is known as the:

• effluent

• electrolyte

• eluent

• mobile phase

The ... phase is the phase that moves over the stationary phase in all forms of chromatography.
