A spectrophotometer is an analytical instrument used to measure the intensity of light at different wavelengths within the visible spectrum or in other parts of the electromagnetic spectrum (e.g., ultraviolet, infrared). It helps quantify how much light is absorbed by a sample, which can be related to its concentration or properties.
Working Principle:
A spectrophotometer works by passing light through a sample and detecting how much light is transmitted or absorbed by the sample at each wavelength. The amount of light absorbed by the sample is typically proportional to the concentration of the substance in the sample, according to Beer-Lambert Law.
Main Components:
Types of Spectrophotometers:
- UV-Vis Spectrophotometer: Measures the absorption of ultraviolet (UV) and visible light (Vis), typically used in chemical analysis, biological studies, and for determining concentrations of solutions.
- Infrared Spectrophotometer (IR): Measures infrared light absorption, commonly used for identifying molecular structures or functional groups in a sample.
- Fluorescence Spectrophotometer: Measures the emitted light after a sample absorbs light, used for sensitive detection of compounds.
Applications:
Advantages:
- Non-destructive: Spectrophotometers do not destroy the sample, making it ideal for repeated measurements.
- Highly Accurate: Provides precise and reliable measurements of absorption or transmission.
- Versatile: Can be used for a wide range of applications in various industries.
Limitations:
- Sample Preparation: Some samples may require preparation (such as dilution or filtration) for accurate results.
- Interference: Other substances in the sample might interfere with the readings if they absorb light at the same wavelengths.
