Calculation Formula

Peak Area = (½ × Peak Height × Base Width)

Where:
Peak Height (y) = Maximum height of the peak
Base Width (w) = Width of the peak base

Peak Area Calculator Usage Guide

Learn how to use the Peak Area Calculator calculator and its working principles in analytical chemistry

How to Use This Calculator

  1. Enter the Peak Height in the first input field. This is the maximum vertical distance from the baseline to the peak.
  2. Enter the Base Width in the second input field. This is the horizontal distance across the peak at its base.
  3. Click the Calculate button to compute the peak area.
  4. The result will be displayed in the Peak Area field.

Working Principle

This calculator uses the simple geometric formula for calculating the area of a triangle:

Area = (½ × Peak Height × Base Width)

This method is commonly used in chromatography and other analytical techniques to estimate peak areas when a Gaussian or similar symmetrical peak shape is observed.

Applications

  • Gas Chromatography (GC) peak area integration
  • High-Performance Liquid Chromatography (HPLC) analysis
  • Quantitative analysis of chemical compounds
  • Peak area normalization in spectroscopy

Important Notes

This calculator provides a basic estimation for symmetric peaks. For more complex peak shapes, more sophisticated integration methods may be required.
