UV spectrometers measure the intensity of light before and after it passes through a sample in a cuvette to determine a solution's concentration, purity, and physical properties. They are ideal for use in industries such as pharmaceutical, biotechnology, food and beverage, chemical, and more. METTLER TOLEDO's UV spectrometers are compact, digital, and easy to use, making them ideal for streamlining your workflows.
A UV spectrometer works by passing light from the ultraviolet (UV) spectrum through a sample and measuring the amount of light that is absorbed or transmitted at different wavelengths. The instrument consists of a light source, a monochromator (to select specific wavelengths), a cuvette holder, and a detector. The detector measures the intensity of the light that passes through the sample, and the data is used to create a spectrum showing the absorbance or transmittance as a function of wavelength.
A UV spectrometer is a type of spectrophotometer specifically designed to measure the absorption of ultraviolet (UV) light. UV light has a shorter wavelength than visible light and can be absorbed by many molecules, including DNA, proteins, and other biological molecules.
While a UV spectrometer is a specialized type of spectrophotometer, the main difference is the range of wavelengths that they can measure. A spectrophotometer can measure light absorption across a wider range of wavelengths, including both UV and visible light. A UV spectrometer is specifically designed to measure UV light, which is often used in applications such as biochemistry and environmental science.
UV spectrometers use a xenon flash lamp as a light source for the UV region. This type of lamp emits a continuous spectrum of UV light, which is necessary for accurate measurements.
Spectrometers are used to analyze the composition and properties of various materials. They can be used to identify unknown substances, quantify the concentration of specific components in a mixture, and study the structure and interactions of molecules.
UV spectrometry, a powerful analytical technique, has a wide range of applications across various fields, including:
