Absorbance Units Full Scale (AUFS) or Absorption Units Full Scale1 is a unit of absorbance intensity that denotes the output of a spectrophotometer. The acronym AUFS can also be written out as Absorbance Units per Full Scale Deflection.2
Usage
AUFS is an arbitrary unit of the maximum ultraviolet or visible light absorbance intensity measured by a detector.3 It can be used in chemical analysis to quantify components in a mixture, as each component's integrated peak area corresponds to their relative abundance. AUFS is given as a number ranging from 0 to 1, where a measurement of 1 AUFS indicates an absorbance reading of 1 at full deflection.1
