
The boat pick-up picks up boat 1 from the sample rack and places it onto the
ceramic hook.

The ceramic hook moves the boat into the TIC reactor. As soon as the boat has
reached the position under the ceramic cannula, the acid addition starts auto-
matically. During the slow boat feed acid is added to the entire sample.

The measuring gas from the purged TIC is passed via the measuring gas drying
and cleaning of the automatic TIC solids module to the detector in the C/S
module.

Boat 1 is then pulled out of the TIC reactor and placed onto the ejection rail.

The sampler picks up boat 2 with the same sample from the sample rack and
moves it directly into the hot zone of the furnace. Here it is incinerated in the
oxygen flow. The total carbon content (TC) is determined in this manner.

The difference of the two measured values (TC-TIC) is then generated and out-
put as TOC result in the program.
During extended measurement interruptions the gas supply can be turned down in the
multiWin program to save gas accordingly. However, the gas supply must be ensured
again in good time (approx. 10 min.) before starting the measurement.
