How to proceed if we want to use detector tubes to identify vapors of isopropyl alcohol and know that vapors of acetone are also present in the air?

a. The reagent coated on the surface of the sorbent material will react only with isopropyl alcohol.

b. Even if vapors of acetone interfere with the reagent, the change of color will be different from the main reaction.

c. We need to know if there are any interferences in the colorimetric reaction and at what concentration levels.

d. Detector tubes are not used if more than one contaminant is present in the air.
