This application describes a flow cell to perform experiments under well-controlled hydrodynamic conditions. The resulting cell enables combining the advantages of in-situ spectroscopic ellipsometry with stagnation point flow conditions. An additional advantage is that the proposed cell features a fixed position of the “inlet tube” with respect to the substrate, thus facilitating the alignment of multiple substrates. Theoretical calculations were performed by computational fluid dynamics and compared with experimental data (adsorption kinetics) obtained for the adsorption of polyethylene glycol to silica under a variety of experimental conditions. Additionally, a simple methodology to correct experimental data for errors associated with the size of the measured spot and for variations of mass transfer in the vicinity of the stagnation point is herein introduced. The proposed correction method would allow researchers to reasonably estimate the adsorption kinetics at the stagnation point and quantitatively compare their results, even when using different experimental setups. The applicability of the proposed correction function was verified by evaluating the kinetics of protein adsorption under different experimental conditions. 1.

A linear variable long pass filter is positioned to filter light reflected from the sample to pass to the image sensor multiple different wave-length bands having different cut-off wavelengths. Wavelengths of light on one side of the cut-off wavelength are blocked and wavelengths of light on the other side of the cut-off wavelength are passed as multiple different long pass wavelength bands for detection by the image sensor. The image sensor detects light for each of the multiple different long pass wavelength bands from the sample. Data processing circuitry converts the detected light for the multiple different long pass wavelength bands for the sample into corresponding different long pass wavelength band data sets for the sample.
