Corrosion in FID Collector and Ignitor Glow Plug
Troubleshooting
Agilent recommends inspecting the collector and ignitor glow
plug for corrosion while performing maintenance on the FID.
The FID combustion process results in condensation. This
condensation, combined with chlorinated solvents or
samples, causes corrosion and sensitivity loss.
To avoid corrosion, keep the detector temperature above
300 °C.
