For unknown samples or the study of analytical conditions as to the wavelength range, the wavelength scan for multi samples is sometimes performed. As the standard installation of UH5300 includes automatic 6-cell turret, the wavelength scan of the inserted cell is automatically performed. For example, when 30 samples are to be measured, the time can be shortened by about 30%
compared to the measurement by a single cell and the work efficiency can be improved.
The absorbance of BTB, a pH indicator, was measured this time. The pH indicators are dyes of which colors change depending on pH and are used not only for pH measurements, but also for LC (liquid chromatograph) post-column methods (LC sheet No. 206).
