Flash Boiling

The mechanisms responsible for flash-boiling injection were investigated. Using an electromagnetic injector developed for this study, propane, methanol and Indolene were heated and injected into a constant-volume vessel. Two regimes of flash-boiling injection were identified. In the first regime, flash-boiling occurs within the injector nozzle without an increase in spray-cone angle. In the second regime, the nozzle exit pressure is sufficiently low that the two-phase compressible mixture created by flash-boiling within the injector nozzle is underexpanded at the nozzle exit and expands externally to increase the spray-cone angle.

Spray Droplets

A spray tower apparatus was developed to emit a constant volume of a solution onto a moving belt of chromatographic paper. A metering and fluid mixing device operating on the principle of continual dilution enables an exponentially varying spectrum of chemical dosages to be sprayed onto the paper strip. The degree of deposit and concentration per unit area on the paper can be altered by nozzle setting and adjustment of the linear speed of the paper strip. The excess spray droplets are removed from the spray chamber by vacuum control.
