Long Optical Path Measurement
Бренд: Shimadzu
Spectrum of Potassium Permanganate
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.
Universal Rectangular Cell Holder, Four-Cell Type
Holds four rectangular cells with an optical path length of 10, 20, 30, 50, 70, or 100 mm.
Note: The Four-Cell Sample Compartment Unit (P/N 206-23670-91) is required. When a rectangular, long-path cell is used on the reference side, its holder (P/N 204-28720) is required.
Reference-Side Rectangular Long-Path Absorption Cell Holder
If using a 4-cell-type universal rectangular cell holder, use this as a reference-side cell holder if necessary.
Long-Path Rectangular Cell Holder
Holds two rectangular cells with an optical path length of 10, 20, 30, 50, 70, or 100 mm.
Cylindrical Cell Holder
Holds two cylindrical cells with an optical path length of 10, 20, 50, or 100 mm.
