Basic Analysis Computations

Two basic analysis algorithms are included in the GC Controller. These are:
Area Analysis - Calculates area under component peak
Peak Height Analysis - Measures height of component peak
Concentration Analysis by Using Response Factor
Concentration calculations require a unique response factor for each component in an analysis.
These response factors may be manually entered by an operator or determined automatically by the
system through calibration procedures (with a calibration gas mixture that has known
concentrations).
Response factor calculation: (using the external standard)
Where:
ARF =
n
HRF =
n
Area =
n
Ht =
n
Cal =
n
Calculated response factors are stored by the GC Controller for use in the concentration calculations,
and are printed out in the configuration and calibration reports.
