Spectrophoto Meters

UV Spectrophoto Meter

Description

A UV spectrophotometer is specifically designed to measure the absorbance of light in the ultraviolet (UV) range of the electromagnetic spectrum, typically between 190 to 380 nanometers (nm). It utilizes a UV light source and a detector to analyze the interactions of UV light with the sample. UV spectrophotometers are widely used in the analysis of organic compounds, including nucleic acids, proteins, and various pharmaceutical substances.

Key Features and Applications of UV Spectrophotometers:

  • UV wavelength range: 190-380 nm
  • Suitable for analyzing samples with UV-absorbing chromophores
  • Typical applications include DNA/RNA quantification, protein concentration determination, enzymatic activity assays, drug analysis, and quality control in pharmaceutical industries.
  • Some UV spectrophotometers allow for scanning across a range of wavelengths to obtain a complete absorption spectrum of the sample.

A spectrophotometer is a more general instrument that measures the absorbance or transmittance of light over a broader range of the electromagnetic spectrum, typically from the UV to the visible and sometimes near-infrared regions. It consists of a light source, a monochromator to select specific wavelengths, a sample holder, and a detector. Spectrophotometers can be further classified based on the range of wavelengths they cover, such as UV-Vis spectrophotometers and visible spectrophotometers.

Key Features and Applications of Spectrophotometers:

  • The wavelength range varies based on the instrument type. UV-Vis spectrophotometers cover both the UV and visible (Vis) range, typically from 190 to 900 nm or 1100 nm, while visible spectrophotometers focus on the visible range.
  • They are widely used for quantitative analysis of various substances, including organic and inorganic compounds.
  • Applications include colourimetric assays, chemical kinetics studies, environmental analysis, food and beverage quality control, and water analysis, among others.
  • Spectrophotometers can perform single wavelength measurements or scan across a range of wavelengths to generate absorption spectra.

In summary, UV spectrophotometers are specialized instruments tailored for analyzing samples in the UV range, while spectrophotometers have a broader wavelength range, including the UV and visible regions. The choice between UV and spectrophotometer depends on the specific application and the range of wavelengths needed for analysis.
