Components for measuring gas drying and cleaning

Dust trap for C/S deter-
mination
The gas flows for carrier gas and combustion gas are controlled through manually ad-
justable flow regulators at the front of the basic device.
An integrated suction pump ensures a stable flow of the measuring gas through the
detector. The required intake flow is set using the "pump" valve at the flow regulator.
The pump and the gas flows are automatically activated once the multiWin program
has been started and the temperature of the combustion furnace differs by less than
50 K from the target temperature. If the temperature differs by more than 50 K from
the target temperature, the pump and gas flows are automatically deactivated.

The dust trap is attached directly to the ceramic combustion tube. Combustion dust
sediments there. Larger particles in the gas flow hit against a plate set vertically to the
gas flow and drop down.
