Long Optical Path Measurement
When the concentration of the sample is too low to be measured using a standard cell with an optical path length of 10 mm, a cell with a longer optical path length is used to enable measurement at the optimum absorption sensitivity. As shown in the figure, the absorption spectrum of potassium permanganate becomes clearer when a 100 mm cell is used instead of a 10 mm cell.
This holder holds 10, 20, 30, 50, 70, and 100 mm square cells.
- For UVmini series, UV-1800/2450/2550/2600/2700/3600 and SolidSpec
- When used on the UVmini series, the sample compartment unit is required. 70 and 100 mm cells cannot be used on the UVmini series
