    Linear range means the range of detection over which the response of the detector is linear, i.e. the response of the detector is a linear function of the concentration of the molecules (or analytes), as opposed to nonlinear. The range is given in decades.

    See http://www.zal.tu-cottbus.de/zal/prakt/gaschrom.htm for some background.

    This site offers a comparison of different detectors and their characteristics such as 'linear range'.
