Standard Deviation given Retention Time and Number of Theoretical Plates Solution

STEP 0: Pre-Calculation Summary

Formula Used

Standard Deviation given RT and NP = (Retention Time)/(sqrt(Count of Theoretical Plates))
σ_RTandNP = (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

Standard Deviation given RT and NP - Standard Deviation given RT and NP is a measure of how spread out numbers are.
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

σ_RTandNP = (t_r)/(sqrt(N_TP)) --> (13)/(sqrt(8))

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
