Application Examples of Hydrogen Flame Detectors
Application Examples of Hydrogen Flame Detectors Details:
Hydrogen flame io nization detector (FID)
Maximum operating temperature: 400℃
Minimum detection limit: ≤2.5*10 -12 g/s(n-C16)
Linear range: 107 (±10%)
Noise≤5×10-14A
Drift≤2×10-13 /30min
automatic ignition
Including: nozzle, igniter, collector, fast heating, signal line, temperature sensing wire, chamber body, etc.
The main feature of the hydrogen flame io nization detector is that it has a respo nse to almost all volatile organic compounds, and the relative respo nse values of all diametric compounds (carbon number ≥ 3) are almost equal. The relative respo nse values of compounds (carbon number ≥ 3) are also almost the same. This brings great co nvenience to the quantification of compounds, and has high sensitivity (10-13~10-10g/s), small ba se flow (10~10A), wide linear range (10~1), dead volume Small size, fast respo nse (1ms), can be used directly with capillary column, insensitive to gas flow rate, pressure and extreme changes, so it has become a widely used gas chromatographic detector.
