The acid is metered with the metering pump by hand. The hose for supplying acid to
the reactor is connected to the metering pump with a valve. The valve in the faucet of
the metering pump must be closed after acid has been supplied to the reactor. This
prevents acid from being inadvertently drawn into the analyzer.
1 Metering pump with scale
2 Recirculation valve
3 Valve for connecting the meter-
ing hose
4 Sealing cap
5 Phosphoric acid bottle

A drying tube, filled with magnesium perchlorate as a desiccant, is installed in the gas
path immediately downstream of the reactor.
The desiccant cartridge is followed by two water traps. The larger water trap (TC pre-
filter) retains aerosol during operation, the smaller water trap (disposable retention
filter) retains rising water.
A halide trap is used to remove interfering substances from the measuring gas and to
protect the detectors and the flow regulator in the C/S module. The U-tube of the hal-
ide trap is filled with a special copper wool and brass wool. The filling of the halide
trap has to be renewed at the latest once half of the copper wool or the brass wool is
discolored.
