TOPwave Operating
55
Start the microwave.
The samples are not evaporated until they are dry. As a rule, a residual volume of 1 – 2
ml remains. In order to concentrate the sample still further, the times in step 1 – 4 must
be increased.
The samples are removed as described in the section "Sample Removal" p. 45.
The evaporated acid is condensed and collected in the two gas scrubber bottles. The acid
is neutralized by the marble granulate. The liquid must be poured off as soon as the gas
scrubber bottles are approx. three-quarters full. The granulate can continue to be used
until it has gone completely into solution. The granulate can neutralize approximately 2
liters of acid. A portion of the acid vapors are also concentrated in the rotor’s collection
vessel. This liquid must be removed after every fuming procedure (see section "Cleaning"
p. 61).
All TFM-PTFE components must be cleaned with water and dried before they are again
used.
