Absorption Accessory

Add UV-VIS Spectrophotometry to your Fluorometer

HORIBA fluorometers have been recognized for their high sensitivity and ability to adapt to various applications due to their modular design. The addition of a simple absorption accessory enhances the performance and versatility of the instrument even more.

In many fluorescence experiments, it is necessary to know the absorption properties of the sample. The ABS-ACC absorption accessory from HORIBA fits directly into a cuvette sample holder and enables the user to measure the absorption spectrum, or check the optical density, of a liquid sample without reconfiguring the fluorometer.

Absorption measurements are complementary to fluorescence. They are necessary for fluorescence quantum yield determination, and more accurate results are usually obtained by using the same optical path for
both fluorescence and absorption measurements. The ability to check the optical density during a fluorescence experiment makes it easy to avoid inner filter effects. By comparing the absorption and excitation spectra, one can draw conclusions about the purity of the sample.

This absorption accessory is very easy to use and enhances a HORIBA fluorometer by offering more versatility. It eliminates the need for a separate, and often expensive, UV-VIS spectrophotometer.
