1.  Introduction to the 220A Olfactometer and hardware set up

Meet the Aurora Scientific 220A Olfactometer…In this 6 minute video, Chris dissects the hardware for the system, explaining in more detail the mass flow controllers, why there are 3, what they do, and how to control them.  Next, he talks about the various connections, from ethernet to in/out valves to DIO2 input and output, before briefly pointing out the numerous LED indicators and what each signify.  In the last portion of this chapter, Chris details the valve manifold, specifically outlining the Vial Valves, Mixing Valve, and the Final Valve.


2.  Overview of configurations and modifications

Endless configuration options…almost!  In the second chapter of this tech cast, Chris details the various modifications and configuration changes that can be made to the 220A Olfactometer to meet your unique research needs.  He begins by sharing a quick start guide to setting up the system in its original 4-vial configuration, before showing how additional sets of 4 vials may be added to the system, up to 16 total vials.  Next, he demonstrates the 3 different methods for filling the vials with odorants, how to handle each one and best practices for executing the filling, removing and replacing of the vials.  And finally, there is a brief description and demonstration of how to replace the tubing in the system.


3.  How to use the 220A Olfactometer

In this final chapter, Chris walks viewers through the Olfactometer Control software, making special mention of key software functions and features.  He demonstrates how to configure the system and vials, set and assign flow rates, generate set and custom sequences, and finally, how to successfully execute odor delivery.
