Subject: formaldehyde sensor


Does anyone know of a formaldehyde sensor that will detect
formaldehyde concentrations exclusive of methanol?

We are trying to mitigate the concentration of formaldehyde (~400
ppm?) in smokestack effluent, but we need to know exactly what we are
starting with to tell how much good we're doing with our remediation
process. The sensor we were looking at will not distinguish between
methanol and formaldehyde. The plan is to put one sensor upstream of
the process and another downstream, hook the whole thing to a PC to
monitor continuously. Flows will be arount 40 cu. ft./min.

Any suggestions?
