Abstract:
Apparatuses and methods for generating trace vapors are provided. The apparatus includes a controller and an oven. The controller includes: a processor, a memory storing at least one control program, a clean solution supply port constructed to output a clean solution, an analyte solution supply port constructed to output an analyte solution, a carrier gas inlet port constructed to receive a carrier gas, and a plurality of carrier gas supply controllers constructed to output the carrier gas. The oven includes a clean manifold, an analyte manifold, a clean solution nebulizer constructed to: receive the clean solution from the clean solution supply port, and the carrier gas from one of the plurality of carrier gas supply controllers, and output a clean solution vapor stream comprising the clean solution and the carrier gas to the clean manifold, an analyte solution nebulizer constructed to: receive the analyte solution from the analyte solution supply port and the carrier gas from another one of the plurality of carrier gas supply controllers, and output an analyte solution vapor stream comprising the analyte solution and the carrier gas to the analyte manifold, a pneumatic valve controllably connected to the processor and communicatively connected to the clean manifold and the analyte manifold, and an output supply port communicatively connected to the pneumatic valve. The controller is configured to operate the pneumatic valve to allow the clean vapor solution or the analyte vapor solution to enter the chamber and be provided to the output supply port.
