Σύνοψη

The purpose of the project is to develop an
electrically controlled evaporator pan to be used in a
chemical procedure described as follows;
In order to monitor large volumes of aqueous samples
for radionuclide contamination , it is necessary to
concentrate the sample'by evaporating the ecxess water and collecting the impurities on a piece of filter paper .The
evaporation must be done under controlled conditions so
that the impurities are not lost due to boiling.
The production of the necessary surface evaporation is
done by using infrared lamps on the top of the sample.This is a time consuming procedure and is carried out overnight.
The evaporation is done proportionaly ie. as the filter
paper dries, the heating produced by the infrared lamps is
reduced until the lamps are finally switched off.
In order to sence the dampness of the filter paper the
project offers the facility of using either a conductivity
sensor or a temperature sensor.
