Retention Time and Relative Retention Time

Description

RT: - Retention time

Definition: -

Retention time is the time taken by the solute to pass through the chromatography column.

It is the time taken by the sample (compound) to elute from the time of injection

The factors that influence the Retention time were 

  1. The flow rate of Mobile phase

Increase in flow rate results in early elution of the analyte there by reducing the Retention time.

  1. The composition of Mobile phase

The change in Mobile phase composition when there two or more buffers to mix, the retention time of the analyte will be altered.

In regular, increase in Organic proportion in the Mobile phase co
