Web8 feb. 2010 · TAG appears to include the critical window of semivolatile compounds, a measurement window that is often ignored in gas-phase studies and particle-phase studies because of interference between the two physical states. This semivolatile organic compound window is roughly defined by vapor pressures ranging between 10-2 and 10 … WebThe term "semi-volatile compounds" refers to organic compounds that possess Henry’s law constants (H) in the range of 10 -5 - 3 x 10 -7 atm*m 3 /mol* and demonstrate higher boiling points, usually greater than that of water with correspondingly low vapor pressure from 10 -14 - 10 -4 atm. *H range defined as volatility from liquid to air.
