Scheibe-Lomakin Equation:
From: | To: |
Definition: The Scheibe-Lomakin equation relates the intensity of a spectral line to the concentration of the emitting element.
Purpose: It's used in spectroscopy to quantify the relationship between element concentration and spectral line intensity.
The equation is expressed as:
Where:
Explanation: The intensity grows with concentration but the exact relationship is modified by the deviation factor.
Details: This equation is crucial for quantitative spectral analysis in chemistry, physics, and materials science.
Tips: Enter the proportionality constant (k), element concentration (G), and proportionality deviation (m). All values must be > 0.
Q1: What is typical value for proportionality constant (k)?
A: The value varies significantly depending on the element and experimental conditions.
Q2: How is the proportionality deviation (m) determined?
A: It's typically determined empirically and accounts for deviations caused by self-absorption.
Q3: What units should be used for concentration?
A: The calculator uses mol/m³, but you can convert from other units before input.
Q4: Can this be used for any spectral line?
A: The equation applies to atomic emission spectra but parameters vary by element and transition.
Q5: How accurate is this equation?
A: It provides a good approximation but actual measurements may require calibration.
