carbon monoxide detectors for boats image
Keith
I am seeing carbon monoxide detectors on my boat false alarm at times. These are both the regular variety and the very sensitive aviation types. There are no boats or engines running nearby, no flames, aerosols in use, no combustion engines of any kind. What other gasses might cause these to false alarm?
Answer
It's possible that the humidity is affecting the performance of the sensors as well. Try running a hair dryer on an open detector to dry out the components.
If you're on the ocean, the salt could be causing issues as well. You'll probably need to switch them out if it's a salt issue, as cleaning them probably isn't an option.

How do I test for the following pollutants in a lab (Environmental Chemistry)?
beltlessbo
Sulfer Dioxide (SO2)
Carbon Monoxide (CO)
Nitrogen Dioxide (NO2)
Ozone (O3)
Lead and Heavy Metals (Pb, Hg, etc.)
Any other that may pertain to this subject.
Thank you.
Answer
Solids like lead and other heavy metals could obtained by filtering the air particles out of the air. They all form insoluble precipitates with carbonic acid (H2CO3).
Ozone can be determined by its sharp smell if in enough concentrations. In Central Florida it is a common smell in the air after a thunder and lightening storm.
NO2 is a brown gas that is easily seen in concentrations in the distant near the horizon.
SO2 can be determined by bubbling the air though water and testing for increased acidity. It also has a sulfur like smell in concentrations.
CO is the most difficult gas. It is colorless and odorless. It will any animal life that is forced to breath it. There are CO detectors that can be bought. I had one in the cabin of my boat which had an inboard gasoline engine.
All of these gases can be detected by a gas chromatograph in a lab.
