There are two main methods for executing odor delivery using the 220A olfactometer, one is using the sequencer to deliver several odorants with a defined duration and order. This is very handy when wanting a random sequence of odors or when using external software or hardware to control timing of odor delivery. The other method which is primarily used for single odor deliveries without a need for timing control when switching vials, involves manually selecting the vial of interest, setting flow rates through the vial and duration of delivery. Once the odor flows to exhaust and the stabilization delay has been reached (set in vial configuration), the odor is ready to be delivered to the animal, as determined by the user.
