Coking

102
Contamination from some sample matrices can reduce
sensitivity. For example, crude oils containing volatile metal
complexes may contaminate the ceramic tubes. In addition,
incomplete combustion of certain hydrocarbon-containing
compounds leaves behind coke deposits on the ceramic tubes.
Coke deposits may be removed from the burner by reducing the
hydrogen flow rate.
