Table 2: Summary of Log (HLC) for PPVE
The Henry's Law constant of PPVE was determined by the ratio of gas-phase concentration over aqueous-phase concentration.
Duplicate test vessels were filled with water and dosed with PPVE gas at three headspace:water ratios (70%, 50% and 30%). The vials were incubated for 5, 6, and 7 days at ambient temperature. Both the headspace and the water phase for each vial were sampled and analyzed in duplicates using gas chromatography/mass spectrometry (GC/MS). The average measured gas phase and water phase concentrations were used to calculate Henry's Law constant for PPVE for each test vessel. Under the conditions of this study (average temperature of 22.6°C), overall average HLC for PPVE is 3200 (%RSD = 13), the overall average log HLC was 3.5 ± 0.06 (% RSD= 1.6).
This study was conducted under GLP compliance with accepted method. Therefore, it is considered reliable without restrictions.
