System for generating tracer particles

A method of generating vapor, comprising:

• receiving a first selection by a user of a fluid having a selected boiling point and a second selection of the fluid having a selected vapor intensity;
• actuating a pump in fluid connection with a fluid reservoir such that the fluid within the fluid reservoir is controlled via a flow controller within a controller to flow at a predetermined fluid flow rate which is dependent upon the first selection of the fluid having the selected boiling point and the second selection of the fluid having the selected vapor intensity;
• actuating a heater in communication with the fluid reservoir such that the heater is controlled via a heater controller within the controller to provide a predetermined heater temperature which is dependent upon the first selection of the fluid having the selected boiling point and the second selection of the fluid having the selected vapor intensity;
• and
• measuring the fluid flow rate via a flow sensor in communication with the fluid reservoir and the flow controller while the fluid is vaporized at the predetermined fluid flow rate and the predetermined heater temperature.

A vapor generating system, comprising:

• a fluid reservoir configured for receiving a volume of fluid to be vaporized;
• a pump in fluid connection with the fluid reservoir;
• a heater in communication with the fluid from the fluid reservoir;
• a controller unit in communication with the pump and the heater, the controller unit comprising a flow controller and a heater controller;
• and
• wherein the flow controller is configured to actuate the pump to provide a predetermined fluid flow rate from the fluid reservoir whereby the predetermined fluid flow rate is dependent upon a selection of the fluid having a selected boiling point, and
• wherein the heater controller is configured to actuate the heater to provide a predetermined heater temperature to the fluid whereby the predetermined heater temperature is dependent upon the selection of a selected vapor intensity at the predetermined flow rate.
