What classes of compounds are not well suited for vapor detection?
The GORE™ Survey has reported compounds as “light” as vinyl chloride through “heavy” compounds up to and including pyrene in the vapor state. Compounds that have very low volatility are generally not good candidates for vapor sampling. Compounds that are highly soluble in water, for example, ketones and alcohols, are typically not available in moist vapor environments, and may not be good candidates for vapor sampling technology. Experience in the field, combined with benchtop experiments, demonstrate compounds should have vapor pressures that exceed ~1.5 x 10-6 mm Hg and a Henry’s law constant exceeding ~1.5 x 10-9 atm m3/mole are needed to be detectable in vapor.
