3.1.4 Components for measuring gas drying and cleaning
The condensation coil and TIC condensation module are mounted on a carrier plate that
is hooked in at the right-hand side of the combustion furnace.
The measuring gas is cooled down quickly in the glass condensation coil and the water
vapor condenses. The measuring gas water mixture is routed to the TIC condensation
container via a hose.
The TIC condensation module in the multi N/C 2100S consists of the TIC condensate
container and the cooling block which surrounds the glass container in the upper part.
In the lower part of the container a glass drip has been integrated for the effective
expulsion of the generated CO
2
. The sample for TIC detection is metered from above
through the TIC lock. Via the top side connection at the glass container the 10%
phosphoric acid for each detection is automatically provided.
The measuring gas is dried by freezing in the cooling block. The dry measuring gas is
routed via the side connection out of the TIC lock out of the condensate container. The
measuring gas drying is maintenance free.
The condensate or the waste solution of the TIC detection is automatically pumped out
via the lower lateral outlet at the glass container.
In the multi N/C 2100S pharma model, the condensation coil and the TIC condensation
module are only used for drying and cleaning the measuring gas.
