Working Volume 20ML Headspace Vials Amber Store Volatile Samples

Jul 04, 2018 · Samples were stored at room temperature (22ºC) prior to analysis. Headspace analysis was performed by placing approximately 1 g of e-juice in a pre-weighed 40 cm 3 amber volatile organic analysis (VOA) vial (actual volume approximately 42 cm 3). The vial plus e-juice was weighed again to determine mass of e-juice.

• If we increase the sample volume, V S, we will reduce the headspace volume, V G , in the same vial and so β will be reduced as a result. Decreasing β will increase the concentration of all compounds in the headspace phase. • If we a variety of compounds present. Each compound vapor will decrease K, for instance by raising the vial
