Question

Match each statement with one of these terms.

a. Elution
b. Mobile phase
c. Chromatogram
d. Stationary phase
e. Retention factor
f. Detector
g. Injection port
h. Carrier gas
i. Theoretical plate number
j. Partition coefficient
k. Retention time
l. None of the above

1. The ratio of the amount of analyte in the stationary phase to the amount in the mobile phase.
2. Time it takes after sample injection into the column for the analyte peak to appear as it exits the column.
3. The process of extracting a component that is adsorbed to a given material by use of an appropriate solvent system.
4. Measure of chromatographic column efficiency. The greater its value, the more efficient the column.
5. Gas, liquid, or supercritical fluid used to transport the sample in chromatographic separations.
6.Immiscible and immobile, it is packed within a column or coated on a solid surface.

Answer 1

1 - e, 2 - k, 3 - a, 4 - i, 5 - b,

Step-by-step explanation:

The ratio of the amount of analyte in the stationary phase to the amount in the mobile phase. --- Retention factor.

Time it takes after sample injection into the column for the analyte peak to appear as it exits the column. -- Retention time

The process of extracting a component that is adsorbed to a given material by use of an appropriate solvent system. -- Elution

Measure of chromatographic column efficiency. The greater its value, the more efficient the column. -- Theoretical plate number

Gas, liquid, or supercritical fluid used to transport the sample in chromatographic separations. -- Mobile phase

Immiscible and immobile, it is packed within a column or coated on a solid surface. -- Stationary phase
