Abstract
A system includes a first aerosolization device (e.g., a nebulizer and a spray chamber/desolvation device in fluid communication with the nebulizer) configured to furnish a first aerosol, and a second aerosolization device (e.g., a second nebulizer and a second spray chamber/desolvation device in fluid communication with the second nebulizer) configured to furnish a second aerosol. The first aerosolization device is balanced with the second aerosolization device. The system also includes an output coupled with the first aerosolization device and the second aerosolization device. The output is configured to supply at least one of the first aerosol or the second aerosol (e.g., to a torch). The system further includes a selection device coupling the first aerosolization device and the second aerosolization device to the output. The selection device is configured to selectively provide at least one of the first aerosol or the second aerosol to the output.
