Measuring the NIR absorption spectra of Holmium and Didymium Glass Filters with the ProNIR Spectrometer
Investigating the absorption and fluorescence pH dependence of Fluorescein, with a a flow cell
In this application note, we study the absorbance and fluorescence pH dependence of a fluorescein aqueous solution, using flow cells. The remaining components used were the LS-LED for fluorescence excitation, the LS-W20 for illumination in the absorbance setup and detection with FLEX RES+ spectrometer for both cases.
Obtaining the blue, green and red colorants in peanut chocolate candies using UV-Vis absorption and reflectance spectroscopy
In this application note, we combine a high-power deuterium tungsten-halogen light source (LS-DWHP) with a FLEX spectrometer in a UV-Vis-NIR absorbance and reflectance configuration (this requires the use of a reflectance probe) to obtain the absorbance and reflectance spectra of the blue, green, and red dyes present in peanut chocolate candies.
