Evaluating the transmittance spectrum and CIELAB color coordinates of red cabbage extract at different pH values
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.
