Abstract: A system for sampling air contained in an appliance shipping container includes a gas analyzer sealably interconnected with a probe by a flexible conduit. Disposed on the lower portion of a side wall of the appliance shipping container is an opening sealably covered by a film patch. A conveyor line arrangement positions the shipping container such that the film patch is disposed adjacent the probe. When the appliance shipping container is detected to be suitably positioned adjacent the probe, an electro-solenoid interconnected with the probe is activated causing the probe to puncture the reflective film patch and permitting an air sample to be drawn from the appliance shipping container into the gas analyzer. If the presence of a vaporized refrigerant is detected, a controller shunts the appliance shipping container to a site for repair of the appliance.
