Width of Peak given Number of Theoretical Plates and Length of Column Solution

STEP 0: Pre-Calculation Summary

Formula Used

Width of Peak N and L = (4*Length of Column)/(sqrt(Number of Theoretical Plates))
w_NandL = (4*L)/(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

Width of Peak N and L - The Width of Peak N and L is defined as the total distance of the base of the peak.
Length of Column - (Measured in Meter) - The Length of Column is the height of the chromatographic column in which the separation of particles takes place.
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

Length of Column: 9.9 Meter --> 9.9 Meter No Conversion Required
Number of Theoretical Plates: 10 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

w_NandL = (4*L)/(sqrt(N)) --> (4*9.9)/(sqrt(10))

Evaluating ... ...

w_NandL = 12.5226195342668

STEP 3: Convert Result to Output's Unit

12.5226195342668 --> No Conversion Required

FINAL ANSWER

12.5226195342668 ≈ 12.52262 <-- Width of Peak N and L
