Halogen trap
The halogen trap removes interfering components (halogens, halogen-hydrogen com-
pounds) from the measuring gas. It also protects the detectors and the flowmeter in this
manner. The halogen trap is installed in the gas path behind the TIC condensate con-
tainer and the water traps.
The halogen trap consists of a U-shaped tube. It is filled with special copper wool and
brass wool. The filling of the halogen trap has to be replaced once half of the copper
wool has changed color to black or when the brass wool has changed color at the latest.
