Acid supply
The acid is metered manually using the metering pump. The hose for the acid supply to the
reactor is connected through a valve to the metering pump. The valve in the cock of the me-
tering pump must be closed after supplying acid to the reactor. This prevents the acid from
accidentally being sucked into the analyzer.

Measuring gas drying and cleaning
The drying tube, filled with magnesium perchlorate as desiccant, is installed in the gas path
directly after the reactor.
The drying cartridge is followed by two water traps. The larger water trap (TC Pre-filter) re-
tains aerosol during operation, the smaller water trap (disposable retention filter) retains ris-
ing water.
The C/S module contains a halide trap for the greatest possible removal of interfering com-
ponents in the measuring gas and to protect the detector. The U-tube of the halide trap is
filled with special copper wool and brass wool. The filling of the halide trap has to be re-
newed at the latest once half of the copper wool or the brass wool is discolored.
