IMT Analytics AG
MultiGasAnalyser is non-sterile. Autoclaving, sterilisation and immersion in liquid can
cause serious damage to the sensor. The sensor can be cleaned with a cloth mois-
tened with ethanol or isopropyl alcohol.
The airway adapter must be changed at least every 12 months. If MultiGasAnalyser
is used in a sterile system, a new sterile adapter must be fitted.
Gas measurements should be checked regularly using a reference measuring instru-
ment.
For this purpose IMT Analytics AG offers a service to recertify the measuring accuracy
of the sensor.

Deviations from gas setting stated. For example, 50 vol% helium typically reduces
the CO
2
values by 6%. This means that a measured mixture consisting of 5.0 vol%
CO
2
and 50 vol% helium is equivalent to a measured concentration of (1-0.06) * 5.0
vol% = 4.7 vol% CO
