Width of Peak given Number of Theoretical Plates and Retention Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Width of Peak NP and RT = (4*Retention Time)/(sqrt(Count of Theoretical Plates))
w_NPandRT = (4*t_r)/(sqrt(N_TP))
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Width of Peak NP and RT - (Measured in Second) - Width of Peak NP and RT is defined as the total distance of the base of the peak.
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.
Count of Theoretical Plates - Count of Theoretical Plates is defined as used to determine column efficiency based on the calculation in which the larger the theoretical plate number the sharper the peaks.

STEP 1: Convert Input(s) to Base Unit

Retention Time: 13 Second --> 13 Second No Conversion Required
Count of Theoretical Plates: 8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

w_NPandRT = (4*t_r)/(sqrt(N_TP)) --> (4*13)/(sqrt(8))

Evaluating ... ...

w_NPandRT = 18.3847763108502

STEP 3: Convert Result to Output's Unit

18.3847763108502 Second --> No Conversion Required

FINAL ANSWER

18.3847763108502 ≈ 18.38478 Second <-- Width of Peak NP and RT

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
3) Partition chromatography
