Number of Theoretical Plates given Retention Time and Standard Deviation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Theoretical Plates given RT and SD = ((Retention Time)^2)/((Standard Deviation)^2)
N_RTandSD = ((t_r)^2)/((σ)^2)
This formula uses 3 Variables

Variables Used

Number of Theoretical Plates given RT and SD - The Number of Theoretical Plates given RT and SD is defined as used to determine column efficiency based on the calculation in which the larger the theoretical plate number the sharper the peaks.
Retention Time - (Measured in Second) - The Retention Time of solute is defined as the time taken by the solute to move over the stationary phase and to come out of the column.
Standard Deviation - The Standard Deviation is a measure of how spread out numbers are.

STEP 1: Convert Input(s) to Base Unit

Retention Time: 13 Second --> 13 Second No Conversion Required
Standard Deviation: 40.83 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

What is Chromatography?

A separation process based on the various partitioning coefficients of different solutes between the two phases.
Involving the interaction of solute(s) and two phases
Mobile phase: A gas or liquid that moves through the column.
Stationary phase: A solid or liquid that remains in place.

What are the types of Chromatography?

1) Adsorption chromatography
2) Ion-exchange chromatography
