MUNRO UV/VIS SPECTROPHOTOMETERS. WAVELENGTH RANGE (NM):190-1100. Type:Single Beam.
UV/VIS spectrophotometers are analytical instruments used to measure the absorption of ultraviolet and visible light by a sample. This absorption pattern helps determine the concentration of substances within the sample, aiding in qualitative and quantitative analysis.
How UV/VIS Spectrophotometers Work
UV/VIS spectrophotometers operate by passing light through a sample and measuring the amount of light absorbed at specific wavelengths. The instrument consists of a light source, a monochromator to select the desired wavelength, a sample holder, and a detector to measure the intensity of light transmitted through the sample.
Applications of UV/VIS Spectrophotometers
Pharmaceutical Industry
In the pharmaceutical industry, UV/VIS spectrophotometers are essential for drug development, quality control, and formulation analysis. These instruments help determine the concentration of active pharmaceutical ingredients (APIs) and ensure the consistency and purity of medications.
Environmental Monitoring
Used in environmental monitoring to analyze pollutants, organic compounds, and contaminants in water, air, and soil samples. They play a crucial role in assessing environmental impact and ensuring compliance with regulatory standards.
Food and Beverage Industry
In the food and beverage industry, they are employed for quality assurance, authenticity testing, and nutritional analysis. These instruments enable the quantification of vitamins, antioxidants, and other compounds essential for product labeling and consumer safety.
Types of UV/VIS Spectrophotometers
UV/VIS spectrophotometers come in various configurations, including single beam and double beam designs.
Single Beam Spectrophotometers
Single beam spectrophotometers measure the absorbance of light by comparing the intensity of light passing through a reference cuvette with that passing through the sample cuvette.
Double Beam Spectrophotometers
Double beam spectrophotometers split the light beam into two paths, one passing through the sample and the other through a reference solution. This design allows for real-time compensation of fluctuations in light intensity, ensuring accurate measurements.
