what does it mean with linear range in detector of GC?

thanks!

Its the range of analyte concentration that gives a "linear response".  For example, your concentration is 1M and your output (peak area)  is 1, then your concentration is 2M and your output is 2, 3M = 3 and so forth.  This is linear response.  Eventually you will get to the point where , say, your concentration is 4M and your output is only 3.5.  Now you have gone out of linear range.  This is just a crude example to illustrate the point.

ahhh! that is a good explanation. thanks, i got it!  :Lighten:
