II.1.1.Corrected CO
Corrected CO is calculated as follows:
If (%CO + % CO
2
)

15 then corrected CO = CO
If (%CO + % CO
2
) < 15 then corrected CO = CO x (15
2
))
II.1.2.Lambda
The lambda value is calculated using the simplified BRETTSCHNEIDER equation as follow:.
Where:
[] = concentration in per cent volume,
K1 = conversion factor for NDIR measurement to FID measurement,
H cv = Atomic ratio of hydrogen to carbon,
