Photophysics

CPL The DSM 172 made by Olis Inc. allow us to do a wide variety of photophysical measurements including:

  • Absorbance.
  • Fluorescence and fluorescence anisotropy.
  • Circular dichroism (CD).
  • Fluorescence detected circular dichroism (FDCD).
  • Circularly polarized luminiscence (CPL).

In most of the cases this different kinds of measurements should be carried out using many instrumentation, but the DSM 172 let us to perform them using just one instrument.

Equipped with a Xe lamp and a monochromator able to select wavelenghts from the near UV to the IR region, the DSM 172 allow us to embrace a wide range of wavelenghts. In other hand, the monochromator have a high sensitivity, meaning really precise measures.

Completely modular, we can modify any variable thanks to their powerfull software and process the obtained data effectively (automatic temperature slope, Singular Value Decomposition, etc...).

Even more, we can measure CPL signals of racemic samples irradiating only one enantiomer and evaluate the optical properties of one enantiomer even when the other one is placed into the sample. We are able to obtain glum values up to 0.0001.
