Function and design

21

The top middle connection on the glass container is connected to the phosphoric acid
pump. The phosphoric acid pump pumps phosphoric acid (10 %) into the TIC reactor for
each TIC determination.

The cooling block dries the measuring gas by freezing out the water vapor. The dry mea-
suring gas is routed via the top connection out of the TIC condensate container. The
measuring gas drying is maintenance-free.

The condensate pump pumps the condensate or waste solution from the TIC determina-
tion out via the bottom side outlet on the glass container after each measurement

Water traps

The water traps remove interfering components from the measuring gas and protect the
detector and the gas box. The water traps are mounted in the gas path behind the cool-
ing block or behind the gas box. The water traps each consist of a larger and a smaller
water trap. The larger water trap (TC prefilter) retains aerosols during operation. The
smaller water trap (disposable retention filter) retains rising water.
