sensor need for Tricresyl phosphate

For gases and dust particles: MSA (Mine Safety Appliances)

For particle segregation/identification: Pacific Scientific Instruments, ROYCO, etc.

Sparkstation,

The patent is not for a sensor to detect tricresyl phosphate, it describes using this compound as a plasticizer used in a sensor to detect other compounds.

Guest, can you provide more information on your application? This compound has a very low vapor pressure. At room temperature, it would never get higher than about 2 ppb. Ppb level sensors tend to be pretty expensive.

Tad

at those trace levels (very low ppb) it seems to me that there is going to have to be a closed system in which a sample is gathered and analyzed.

Now as to how portable? That's another question. You would have to have ultrapure sampling methods to maintain sample integrity. GC ( if feasable) is becoming more portable all the time.

If you are wanting to monitor levels in atmospher as a result of a particular process that you are performing (ie realtime) then that is another ball of worms of a different color.

Any more details you can give up?
