NRTandSD = ((tr)^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
