Samples are placed in cells for measurements. The figure above shows the ten available shapes of sample cells. Generally, the square cell with an optical path length of 10 mm is used. However, in cases where absorption is low, a cell with a longer optical path length is used, whereas when absorption is high, a cell with a shorter optical path length is used. The following describes the relationship between absorption strength (absorbance) and optical path length. This formula can be used to determine the appropriate optical path length.
