Maintaining the FID 8
Maintaining Your GC 151
Selecting an FID Jet
Open the oven door and locate the column connection fitting at
the base of the detector. It will look like either a capillary
optimized fitting or an adaptable fitting.
• If you have an application that tends to clog the jet, select a
jet with a wider tip id.
• When using packed columns in high column-bleed
applications, the jet tends to clog with silicon dioxide.
• In simulated distillation applications, the high-boiling
hydrocarbons tend to clog the jet.
For capillary optimized fittings, select a jet from Table 24. For
adaptable fittings, select a jet from Table 25.
