The GSF setup (Gas Scale Factor) is critical for obtaining quantitatively correct results.  It 
accounts for the fact that moisture molecules have different absorption features in different 
buffer gases.

The GSF should be applied when the user has any knowledge of a change in the buffer gas 
or change in the percentages of a mixed background gas.  The default setting from the 
factory is 100% N

, yielding a GSF of 1.00.
