Measuring gas drying and cleaning

TIC condensation module
The analyzer features a specially developed UV reactor with an integrated UV radiation
source made of quartz glass. The reactor directly surrounds the UV radiation source.
Wavelengths 185 nm; 254 nm are used to oxidize samples. Thanks to its high radiation
density, the UV radiation source digests the samples very well.
The UV reactor has two inlets and one outlet. The syringe pump feeds the sample and
the reagent into the reactor via one inlet. The second inlet feeds in the carrier gas. The
hose system transports the measuring gas further to the TIC condensate container via
the top outlet.

The TIC condensation module consists of a TIC condensate container and a cooling
block. The TIC reactor and the gas/liquid separator are combined in the TIC condensate
container. The cooling block dries the measuring gas at the same time.
The TIC condensation module is located on the front side. The TIC condensate container
has four connections. The right side connection connects the TIC condensate container
with the UV reactor. The wet measuring gas/carrier gas mix is supplied via the connec-
tion. The gas is routed downward in the condensation module and exits via a glass drip.
The integrated glass drip ensures the effective purging of the generated CO
The cooling block dries the measuring gas by freezing out the water vapor. A Peltier ele-
ment provides cooling. The dry measuring gas is routed out of the TIC condensate con-
tainer via the top left connection. The measuring gas drying is maintenance-free.
The syringe pump routes the sample and reagents into the TIC condensate container be-
fore each measurement via the bottom connection and hose 1. The fourth connection is
connected to the condensate pump. The condensate pump removes the waste from the
TIC condensate container.
