UV/VIS Spectroscopy Determines Known and Unknown Substances.


Reliable and Accurate Results

UV/VIS spectroscopy is an indispensable method in modern analytical laboratory. It is well-established, reliable and accurate.

Using UV/VIS Spectroscopy:
  • Unknown substances can be identified. 
  • The concentration of known substances can be determined.

Merck provides you with a wide range of equipment and tools for your spectroscopic analysis: solvents, spectrophotometers, and standards.

Solvents for UV spectroscopy must have good dissolving properties and transmit UV light over a wide UV range. Merck’s Uvasol® range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity.

Combining the benefits of a system photometer with the versatility of a spectrophotometer, Merck’s Spectroquant® Pharo 100 and 300 spectrophotometers open up the possibilities for your analysis. Whether you wish to program your own methods, measure concentrations or absorbances, record spectra and kinetic profiles, or perform multiwavelength measurements, Merck spectrophotometers make all applications possible – and easy.

UV/VIS spectrometers must be checked regularly for correctness and uniformity of results and function – and documented as such. For the qualification of your UV/VIS photometer, Merck is supplier of UV/VIS standards Certipur®.
