Gas Inlets: Carrier (H2, He, N2), Make-up gas (H2, He, N2), Detector Fuel Gas (depending on the detector type).

Pneumatic controls: These controls regulate the correct gas pressure and then fed to the required part of the instrument.

Injector: Here the sample is volatilized. Many inlet types exist including split/splitless, programmed thermal vaporizing (PTV) and Cool-on-column (COC).

Column: The sample is separated into its constituent components in the column. Columns vary in length and internal diameter depending on the application type and can be either packed or capillary.

Column Oven: Temperature is controlled via a heated oven. The oven heats rapidly to give excellent thermal control. The injector and detector connections are also contained in the GC oven.

Detector: The detector responds to a physicochemical property of the analyte, amplifies this response and generates an electronic signal for the data system to produce a chromatogram. Main detectors are Flame Ionization (FID), Electron Capture (ECD), Flame Photometric (FPD), Nitrogen Phosphorous (NPD), Thermal Conductivity (TCD), and Mass Spectrometer (MS).
