Abstract
This document generally describes a system and method configured to generate vapor samples from one or more smoking articles used for testing purposes. The system can be configured in a manner that generates a predetermined flow profile by driving a fluid pump in a scheme that accounts for fluid inertia.
Claims18
A system comprising:
- an aerosol-sensor positioned in a flowpath;
- a fluid pump capable of producing a flow of smoking article vapor, at a variable velocity, along the flowpath to the aerosol-sensor;
- a pump controller communicably coupled to the pump and comprising a processor;
- computer memory storing instructions that, when executed by the processor, cause the pump controller to perform operations comprising:
- activate the fluid pump in a first direction for a first time at an overshoot velocity;
- activate the fluid pump in the first direction for a second time after the first time at a target velocity less than the overshoot velocity;
- activate the fluid pump in a second direction for a third time after the second time at a reversal velocity;
- and
- activate the fluid pump for a fourth time in the second direction after the third time at a second reversal velocity less than the reversal velocity.
