• Distribution

According to the mechanism involved in differential migration of the solutes, chromatographic techniques are classified into planar and columnar

• True

• False

Removal of adsorbed solutes from stationary phase using eluent is known as



• Eluate

• Effluent

• Elution

• None of the above

A mode of analysis that involves the addition a solvent mixture of fixed composition during the

whole process.

• Linear elution

• Frontal analysis

• Fractional elution

• Isocratic elution

The volume of the mobile phase that comes out the column before elution of any solutes is known as retention volume
