ABSTRACT:
Methods and apparatus for rapid gas recovery in a controlled gas atmosphere enclosure, which are particularly suited for maintaining incubator gas concentration levels, include the formulation of algorithms utilized for this purpose. The algorithms are included in the firmware for an embedded controller and operate gas solenoids that have inputs defined as specific gases at a defined pressure. An application of the rapid gas recovery method and apparatus to incubators is also disclosed.
