How long is the average life span of a Flame Ionization cell?
This item can last the life of the instrument under ideal conditions. If the sample is very clean, and the sensor vent is not restricted such that condensation does not build-up in the FID chamber. There could be component failure, the coil can overheat. The collector walls can become contaminated, causing loss of sensitivity. In most cases I would say that the cell-plate assemblies usually last 5+ years.
