Once the Model GFC 7000TA has computed this ratio, a look-up table is used, with interpolation, to linearize the response of the instrument. This linearized concentration value is combined with calibration SLOPE and OFFSET values to produce the CO2 concentration which is then normalized for changes in sample pressure.

9.1.4. Interference and Signal to Noise Rejection

If an interfering gas, such as H2O vapor is introduced into the sample chamber, the spectrum of the IR beam is changed in a way that is identical for both the reference and the measurement cells, but without changing the ratio between the peak heights of CO2 MEAS and CO2 REF. In effect, the difference between the peak heights remains the same.
