Applications With Corrosive Or Solvent Components
Special paramagnetic oxygen sensors are
available to measure gases, containing cor-
rosive or solvent components.
See below tables for further information on
approved solvents, and medium affected
materials.
Approved solvents
(inclusive accompanying
disturbing components)
Acetic acid
Acetone
Acrolein
Aromatics
Butadiene
Butadiene-1
Butadiene-2
C2H2
C4H8
C5
C6H12
CH3COOH
Cyclohexane
Cyclohexanon
Dimethyl sulfide
Ethanol
Ethene
Ethylene
Ethylene oxid
Conditions
• Single or summarized concentrations
do not exceed 20 %
• Gas passes gas cooler prior to entering
the analyzer
• Gas dew point at max. 5 °C
Solvent resistant sensors have limited
lifetime and are consumables!

medium affected materials
Another variation of measuring cell has the
following materials in contact with the sample:
A316 stainless steel, viton 'O' ring, boro-
silicate glass, electroless nickel, platinum,
platinum/iridium alloy.
For the solvent resistant version of this cell,
the 'O' ring made of viton is replaced by a
chemraz
model.
