Cuvette spectroscopic measurements

All spectroscopic measurements were done at approximately 23% R.H. by keeping the slide in a sealed cuvette under a constant flow of argon humidified in a saturated NaCl solution.The film capacitance values were measured periodically during data collection. ... 

The principles and operation of UV /VIS spectroscopic detectors are discussed at length in Section 5.2.4. The detector in HPLC refers to the whole spectroscopic assembly, whose design is optimized to make rapid, continuous measurements of solutions passing through a flow cell of volume much smaller than the typical sample cell or cuvette of a conventional spectrometer. The light source, optical train, dispersion device, and light detectors are similar in design to those discussed in Chapter 5, but they are often built on a... 

The PI curves are usually spectroscopically performed in cuvette scale and in minute timescale. To measure the specific growth rate as a function of hght intensity in analogy to the Monod equation, cultivations have to be performed allowing appropriate acchmation of the cells. Aiba (1982) formulated the observable growth rate as substrate inhibition ...
