Abstract
A gas chromatography (GC) system includes a primary complete, independently-operable, self-contained GC system and a secondary, dependently-operable GC system. The primary and secondary systems have two independently controlled GC ovens. Injectors and detectors are supported by heater blocks or ovens mounted on the respective GC ovens and are connected to the electrical and pneumatic controls of the primary GC system. The injectors and detectors of the secondary GC system share operation of the primary GC system. GC columns can be mounted in each oven and operated completely independently or dependently in different ways. A separate power supply for the secondary oven is connectable to a separate circuit or power line in the user environment.
