Maintaining Your GC 201
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 32.
For adaptable fittings, select a jet from Table 33.
