A pair of cells with closely similar optical properties are called matched cells. One cell is the sample cell while the other, the reference (or blank) cell contains the solvent or a reference solution. In @D01842@, radiation is passed either simultaneously or alternately through the cells. In single beam instruments the cells are moved sequentially into the radiation beam.
