Measuring gas drying in the standard version
Concentrated sulfuric acid is used for drying the measuring gas. The sulfuric acid
container (vertical) has a capacity of 40 ml. This capacity is enough for processing up
to 100 samples. In the standard version, the sulfuric acid container is attached to the
furnace and directly connected to the open combustion tube via a spherical joint.
The sulfuric acid container (vertical) and the measuring cell in the chlorine module are
connected via a spherical joint adapter with a hose. The intake pump in the chlorine
module transfers the measuring gas to the measuring cell.

Auto-protection assembly (optional)
The multi-purpose combustion tube requires the use of the auto-protection assembly
(APB). The assembly has the following purpose:
Coupling the multi-purpose combustion tube with the other measuring gas paths
Filtering solid particles, aerosols and liquids
The auto-protection assembly is attached to the furnace housing with a clamping
mount.
