WebThe detectors that can be used with Shimadzu gas chromatographs are shown below. They are broadly divided into general-purpose detectors and selective, high-sensitivity detectors. General-purpose detectors can analyze a wide range of compounds, of which the flame ionization detector (FID) is the most common because it can analyze almost all ... WebApr 14, 2015 · 3. 3 b. Flame Ionization Detector (FID) This is one of the most sensitive and reliable destructive detectors. Separate two gas cylinders, one for fuel and the other for O2 or air are used in the ignition of the flame of the FID. The fuel is usually hydrogen gas. The flow rate of air and hydrogen should be carefully adjusted in order to ...
WebFlame Ionization Detector (FID) - Uses a hydrogen flame to produce ions. More difficult to operate than PIDs. Less sensitive to effects of humidity. Respond to greater number of organic chemicals (C-C or C-H bonds). Unit is linear over a greater range. Ionize materials with IP of 15.4 eV or less. Vapor sensitivity dependent on energy required to WebThese rack-mountable continuous Hydrocarbon Analyzers are accurate, reliable, and linear. Flame Ionization Detector. Automatic FID Ignition and Shutoff. Automatic user-defined calibration. Continuous unattended operation. Multipoint sampling options. Select a product from the list below to discover more.
WebA portable FID uses a hydrogen-air flame to combust the sample in a carrier gas (usually air) and detect its concentration by measuring the . generation of liberated ions (charged atoms or molecules). The flame is surrounded by a high polarizing voltage produced by two electrodes located near the flame (Figure 1).
