AUFS

For the file system, see aufs.

Absorbance Units Full Scale (AUFS) or Absorption Units Full Scale^[1] 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]
