Placing UV detectors far away from a chromatographic column can be problematic. The increased extra column volume can cause band broadening, reducing the efficiency of a separation. Also, experiments ...

UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample in comparison to a reference ...

The need of highly accurate wavelength measurements necessitates calibration and long-term stability in the measuring instrument. For precise, continuous wavelength measurement, a continuous reference ...
