The FID detector periodic maintenance includes:
• Cleaning the collecting electrode
It is suggest to clean the collecting electrode annually, or when a high noise baseline is
found, due to some compounds that produce detector contamination. If necessary,
replace the collecting electrode.
See
“Cleaning or Replacing the FID Collecting Electrode”
• Replacing the FID ignition glow-plug
This operation is NOT part on the ordinary maintenance. The flame ignition element
must be replaced only when defective.
See
“Replacing the FID Ignition Glow-plug”
Before maintaining the detector, read the following precautions:
WARNING
Carry out all the operations at low temperature to avoid burns. Therefore,
before beginning maintenance, cool the detector to room temperature.
CAUTION
When handling organic solvents you must take precautions to avoid health
hazards.
