DATA COMPUTATIONS C-7
MON2000
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.

n
concentration of component “n” in mole percent
AREA
n
area of component “n” in unknown sample
ARF
n
response factor of component “n” calculated
from area of calibration sample. Units are area
per mole percent
Ht
n
peak height of component “n” in unknown
sample
HRF
n
response factor of component “n” calculated
from peak height of calibration sample. Units
are height per mole percent
