Summary

Vapors and aerosols of the same or different chemical(s) can be present concurrently during certain operations. For example, semivolatile organic compounds may have a vapor pressure that allows them to exist as both vapors and aerosols. Generally the aerosols are collected on a filter while the vapor phase is collected on a sorbent tube. Care must be taken during the sampling so that all of the molecules are collected in order to accurately determine the airborne concentration.
