GC-MS System Schematic Diagram

A GC-MS system couples a gas chromatograph to a mass spectrometer so that compounds are first separated by the GC column and then identified by the mass spectrometer. The schematic shows the injector, carrier gas, column, ion source, mass analyzer, and detector as a connected instrument chain.

A sample is vaporized at the injector and carried by an inert gas through the GC column, where compounds separate by how strongly they interact with the stationary phase. Each compound then enters the ion source, is ionized, sorted by mass-to-charge ratio in the analyzer, and counted at the detector to produce a spectrum.

A GC-MS block diagram usually shows the carrier gas supply, the injector port, the heated chromatography column inside an oven, the interface, and the mass spectrometer section — ion source, mass analyzer, and detector — followed by the data system that records the signal.

You can generate a GC-MS schematic on SciFig: describe the instrument or workflow, and SciFig produces an editable block diagram of the injector, column, and mass spectrometer. You can then relabel each part and export the figure for a paper, slide, or poster.

Gas chromatography separates a mixture into individual compounds over time, but it does not identify them on its own. The mass spectrometer adds identification by ionizing each separated compound and measuring its mass-to-charge ratio, giving both separation and structural confirmation in one instrument.

Yes. After generating the schematic you can open it in SciFig's editor to vectorize it into clean SVG, relabel the injector, column, ion source, analyzer, and detector, adjust the layout, and export it in the format your journal or presentation requires.
