Document Revision: ERAVAP_a-8018 10
A typical measurement with ERAVAP can be described as follows:
The sample tube is put into the sample container (1). After starting the measurement, the
measuring cell (6) is regulated to the specified filling temperature and the piston (9) moves to
the down position simultaneously the outlet valve (4) is opened to release the pressure. The
outlet valve is the closed, the inlet valve (2) is opened and the piston moves upwards to
introduce the sample into the measuring cell. The piston then is reset to the down position
again to expel the liquid via the outlet valve.
After this rinsing procedure has been repeated a pre-defined number of times, the piston draws
in a specified amount of sample, then the inlet valve is closed. The piston moves further up
(extension against vacuum) and the measuring cell is regulated to the specified measuring
temperature.
When a pre-defined measuring time is elapsed the pressure inside the measuring cell is
determined by the pressure sensor (9) and used for calculating the method dependent result
data.
