Modular gas chromatograph

摘要

This invention is related to a gas chromatograph wherein more substitutable modules are foreseen, in particular injector modules and/or detector modules, as well as one embodiment in an oven module. Each module is insertable in a seat of the gas chromatograph mainframe with fast connections of its electronic and pneumatic means to corresponding outlets on said mainframe. Each module has its own heating element.

主权项

1. A gas chromatograph comprising a mainframe housing an oven wherein at least one capillary column is installed, at least one injector, at least one detector, at least one heater and at least one electronic controller for controlling the temperature of the oven, injector(s) and detector(s), the feeding of gases to the injector(s) and detector(s) and the analysis process, wherein at least one injector and/or one detector is in a replaceable modular form, each module comprising:
mechanical connections to said mainframe; pneumatic connections with gas feeding outlets on the mainframe; one or more connection(s) to connect the capillary column(s) end(s) to the injector or detector body of the module; connections with electrical-electronic outlets on the mainframe; a heater for the module; and a dedicated electronic controller for controlling at least the temperature and the gas feeding features of the module.
