The basis for determining the concentration of followed species is Lambert-Beer law which establishes the connection between the optical absorbance A of the colored solution, thickness of the photometrical layer b, molar absorption coefficient a and the concentration c of the species observed:
Based on the experimental data obtained with the use of optical absorbance and luminescence spectroscopy as well as on the results of electrochemical and EPR measurements and the data of chemical analysis, we can conclude that the interaction of MDMO-PPV with heteropolyacids leads to the formation of strong charge-transfer complexes.
The use of RPE as the core protein provided a distinctive optical absorbance that facilitated both the HPLC characterization and the measurement of molar concentrations of the final released conjugates.
The FIA-SIA-LOV unit was developed by flow injection system supplier FIAlab Instruments, and is compatible with Ocean Optics UV and Visible miniature fiber optic spectrometers, light sources and optical fibers for dynamic spectral analyses of optical absorbance or fluorescence of fluids.
was measured in isolated PSII reaction centers with optical absorbance spectroscopy, a result consistent with [Y.
