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.

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

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 ...

Ensure solute is fully dissolved and no precipitation or aggregation has occurred. Best practice: Always run a calibration curve with standards of known concentration to verify linearity and determine ...
