Application Examples of Hydrogen Flame Detectors Details:

Hydrogen flame ionization 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 ionization detector is that it has a response to almost all volatile organic compounds, and the relative response values of all diametric compounds (carbon number ≥ 3) are almost equal. The relative response values of compounds (carbon number ≥ 3) are also almost the same. This brings great convenience to the quantification of compounds, and has high sensitivity (10-13～10-10g/s), small base flow (10～10A), wide linear range (10～1), dead volume Small size, fast response (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.
