Linear range- in detector of GC

Click For Summary
SUMMARY

The linear range in Gas Chromatography (GC) detectors refers to the concentration range over which the detector's response is directly proportional to the concentration of analytes. This linearity is crucial for accurate quantification of substances. The linear range is typically expressed in decades, indicating the span of concentrations that can be reliably measured without deviation from linearity. For further details, refer to the comparison of different detectors and their characteristics available at the provided link.

what does it mean with Linear range in detector of Gas Chromatography?

thanks!
 
Chemistry news on Phys.org
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'.
