The
neccessary accuracy (typical 10-50 µm) of particle size determination and
the typical size of the membrane (26mm to 50mm) requires that the mebrane
has to be recorded in segments.

| The dried filter
membrane is put onto the filterholder which comes with the system. After
choosing the specification associated with the filter all evaluation is
done without user interaction. His remaining task is to check the
measurement result for artefacts and eventually print out the report. The
neccessary accuracy (typical 10-50 µm) of particle size determination and
the typical size of the membrane (26mm to 50mm) requires that the mebrane
has to be recorded in segments. |

The result of residue analysis is presented in a table:
 |
After finishing the analysis,
the program switches to a mode, where the user can check the result.
Particles are ordered by size. After checking the result, no further user interactions are neccessary. Report generation is done automatically. |
