Introduction

Absorption spectroscopy is a technique used to determine the concentration and identity of substances via absorption of electromagnetic radiation. It plays a crucial role in various fields such as chemistry, physics, and biology.

Principles of Absorption Spectroscopy

This technique is based on the principle that molecules absorb light at specific wavelengths corresponding to electronic transitions. According to Beer-Lambert Law, the absorbance (A) is directly proportional to the concentration (c) of the absorbing species and the path length (l) of the sample: A = εcl, where ε is the molar absorptivity.

Measurement and Analysis

Absorption spectroscopy measurements involve directing a beam of light at a certain wavelength through a sample. A detector measures the intensity of light before and after it passes through the sample. The ratio of these intensities is used to calculate absorbance.

• Wavelength Range: Typically from 200 nm (ultraviolet range) to 800 nm (visible range).
• Resolution and Sensitivity: High-resolution spectrometers can distinguish between closely spaced absorption lines. Sensitivity depends on the detector and the noise level.

Applications

Absorption spectroscopy is utilized in various applications including:

• Quantification of nucleic acids and proteins in biological samples.
• Detection of pollutants in environmental monitoring.
• Analysis of food and beverages for quality control.
