It can separate different substances of a complex mixture. In our laboratory, we commonly use it to assess the chemical reactivity of our materials. Our model, Agilent 6890N, offers a dual channel design with two different inlets. The column installed in the chromatograph is an Agilent 199091J-413 HP-5 with the following dimensions: 30m x 320 µm x 0.25 µm and is able to work up to 300ºC. Our detectors include a Flame Ionization Detector (FID) and a Thermal Conductivity Detector (TDC) and we commonly use nitrogen as a gas carrier.
