The DeNovix™ DS-11 Series Spectrophotometer / Fluorometer facilitates precise absorbance and fluorescence quantification over an extensive dynamic range. The dual-mode spectrophotometer features ...

Absorbance methods measure the amount of light absorbed by a sample at a specific wavelength. The absorbance is directly proportional to the sample's concentration, enabling accurate quantification.

Fluorescence spectra are often subject to significant distortions. These are largely predictable and are caused by concentration-dependent Inner Filter Effects (IFE). It is therefore the ...
