Retention Time given Number of Theoretical Plates and Standard Deviation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Retention Time given NP and SD = (Standard Deviation)*(sqrt(Number of Theoretical Plates))
t_{NP_SD} = (σ)*(sqrt(N))
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

Retention Time given NP and SD - (Measured in Second) - Retention Time given NP and SD 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.
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.

STEP 1: Convert Input(s) to Base Unit

Standard Deviation: 40.83 --> No Conversion Required
Number of Theoretical Plates: 10 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_{NP_SD} = (σ)*(sqrt(N)) --> (40.83)*(sqrt(10))

Evaluating ... ...

t_{NP_SD} = 129.115796864675

STEP 3: Convert Result to Output's Unit

129.115796864675 Second --> No Conversion Required

FINAL ANSWER

129.115796864675 ≈ 129.1158 Second <-- Retention Time given NP and SD

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
