Known interferences
|
Interferences
(cross-sensitivity) are found for alcohols > 5%; hydrogen peroxide (H2O2)
> 3%; sodium hypochlorite (NaClO; commercial
bleach) > 3%; gaseous sulfur dioxide (SO2); and gaseous
chlorine (Cl2).
The
In-Situ® optical DO sensor should not be used in organic solvents,
such as acetone, chloroform or methylene chloride,
which may swell the foil matrix and destroy it.
No cross
sensitivities exist for carbon dioxide (CO2), ammonia (NH3),
pH, any ionic species like sulfide (S2-
), sulfate (SO42-), chloride (Cl-), or hydrogen sulfide (HS-).
