Fido isn't for airport security. It's for small applications where you want to inspect explosive traces in particular situations. As far as I know it's single use, and you have to replace the polymeric/chemical sensor on each application.

Fido sensing elements are generally good for many hours of operation. The PaxPoint product is specifically intended for liquid screening in airports. The main limitation is that they need a focused target to work on. The holy grail is a walk-through chemical sensor, but the physics of that is challenging.
