Absorbance measurements in fluids can be done in different setups and wavelength ranges, like with fiber optic dip probes or flow cells for in-line absorbance or a cuvette holder for absorption measurement in a sample. For UV/VIS measurements a spectrometer can be configured with a range from 200 to 1100 nm and a spectral resolution of 1.4 nm FWHM. Further a combined deuterium-halogen light source is needed. For the different applications different probes can be used. A typical setup for absorption measurement is shown below.
Components used in the absorption measurement setup are depicted in the following table:
