The Starna Rhodamine B Quantum Counter Cell is designed for use in quantum yield determination and spectral response factor measurement. It contains a high concentration of Rhodamine B dissolved in an organic solvent, sealed permanently inside a triangular, far UV-quality quartz cell. The cell is intended for spectrofluorometer applications where a small portion of excitation radiation is directed onto its front surface to produce fluorescence proportional to the excitation intensity.
This device facilitates unity quantum conversion, meaning a one-to-one relationship between excitation and emission intensities. The emitted fluorescence is detected by a photomultiplier, enabling calculation of spectral response factors and the generation of corrected fluorescence spectra. The cell offers a flat absorbance profile over a usable spectral range of 220 nm to 580 nm, with emission at Rhodamine B’s maximum (~630 nm) remaining independent of excitation wavelength.
