JULY 2010 Conc. Analysis with Response Factor
Calc. in Mole Percent w/o Normalization
Once response factors have been determined by
the controller or entered by the operator,
component concentrations are determined for
each analysis using the following equations:
where
Note that the average concentration of each
component will also be calculated when data
averaging is requested.

or
CONCnconcentration of component “n” in mole percent
AREAnarea of component “n” in unknown sample
ARFnresponse factor of component “n” calculated
from area of calibration sample. Units are area
per mole percent
Htnpeak height of component “n” in unknown
sample
HRFnresponse factor of component “n” calculated
from peak height of calibration sample. Units
are height per mole percent
