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

STEP 0: Pre-Calculation Summary
Formula Used
Half of Average Width of Peaks = (sqrt(5.55/Number of Theoretical Plates))*(Retention Time)
w1/2av = (sqrt(5.55/N))*(tr)
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
Half of Average Width of Peaks - (Measured in Second) - The Half of Average Width of Peaks is the addition of the width of the number of peaks divided by twice the total number of peaks.
Number of Theoretical Plates - The Number 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.
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.
STEP 1: Convert Input(s) to Base Unit
Number of Theoretical Plates: 10 --> No Conversion Required
Retention Time: 13 Second --> 13 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
w1/2av = (sqrt(5.55/N))*(tr) --> (sqrt(5.55/10))*(13)
Evaluating ... ...
w1/2av = 9.68478187673837
STEP 3: Convert Result to Output's Unit
9.68478187673837 Second --> No Conversion Required
FINAL ANSWER
9.68478187673837 9.684782 Second <-- Half of Average Width of Peaks
(Calculation completed in 00.004 seconds)

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
4) Molecular Size exclusion chromatography
5) Affinity chromatography
