RF
i
Area or height average response factor for component
n
from the calibration
run
k
Number of calibration runs used to calculate the response factors
The percent deviation of new
RF
averages from old
RF
average is calculated in the following
manner:
where the absolute value of percent deviation has been previously entered by the
operator.
Concentration calculation - mole percentage (without
normalization)
After response factors have been determined by the controller assembly or entered by the
operator, component concentrations are determined for each analysis by using the
following equations:
where:
ARF
n
Area response factor for component
n
in area per mole percent
Area
n
Area associated with component
n
in unknown sample
CONC
n
Concentration of component
n
in mole percent
Ht
n
Peak height associated with component
n
mole percent in unknown sample
HRF
n
Peak height response factor for component
n
Component concentrations may also be input through analog inputs 1 to 4 or may be
fixed. If a fixed value is used, the calibration for that component is the mole percent that
will be used for all analyses.
Concentration calculation in mole percentage (with
normalization)
The normalized concentration calculation is:
