(3) Interference at the indicated gas level. For example, 50 vol% Helium typically decreases the values read in
CO
2
by 6%. This means that if the mixture contains 5.0 vol% CO
2
and 50 vol% Helium, the CO
2
concentration
measurement will normally be calculated as follows:
(1 - 0.06) * 5.0 vol% = 4.7 vol% CO
2
.
