Experiments in which H2O (ACS de-ionized reagent grade) was introduced into the gas phase required the use of a vaporization system. The vaporization system consists of a syringe pump, nebulizer, and heated vaporization chamber shown in Fig. 2. H2O mass flow rates were controlled using high precision syringe pumps; a Harvard Apparatus PHD 2000 for p = 1 atm experiments and a Chemyx Nexus 6000 syringe pump for elevated pressure experiments.
