Functional principle
The CTM-EF module is an extraction module for component sampling using
rinse extraction. This module may be used with the CTM-SC-1xxx, CTU
1x4x-x-x-F, CTU 1x4x-x-x-A supply modules.
These components are rinsed off in a test liquid with a defined cleanliness.
At the end of the sampling process, the entire liquid with its particle load is
sucked via the membrane retainer. The rinsing liquid (now referred to as the
analysis liquid) that carries the rinsed off dirt particles is drawn through the
analysis membrane by means of vacuum and returned through connection
"R" to CTM-SC-1xxx, CTU 1x4x-x-x-F, CTU 1x4x-x-x-A.
The analysis membrane is then analyzed. The results provide information on
the type, size and mass of contamination.
Knowing what type of contamination is involved enables measures to be
taken to prevent it (improved filtration, transportation, storage, etc.).
