The Smart VacPrep is an advanced six-port degassing system that utilizes vacuum to degas samples by
heating and evacuation. Each of the ports may be operated independently of one another. Samples may
be added or removed from degas ports without disturbing the treatment of other samples undergoing
preparation. When starting a new sample, ports already degassing samples are automatically suspended
unless they are in the slow evacuation stage. When unrestricted evacuation is attained by the new
samples, the previously suspended samples will automatically resume their evacuation. Degassing will
automatically terminate when each sample has completed all programmed steps.
The Smart VacPrep remembers the previously selected set of degas conditions and allows them to be
reused. However, the option of programming each port with a different set of parameters is available. A
record of the sample preparation time and temperature can be recorded as part of the sample data file.
The degas program may be started or terminated by using the analyzer software on the computer
attached to the analyzer or with push buttons on the front panel of the Smart VacPrep. The push button
control on each port provides the ability to attach the sample tube with heating mantle, and immediately
start degassing a sample.
There are two methods of starting the degas process from the analyzer software:
l
Start Degas menu option. Accessed from the Smart VacPrep > Unit [n] > Start Degas menu selec-
tion. Provides the option to use degas conditions from selected sample files or a degas conditions files
for each Smart VacPrep port. When using the
Start Degas menu option, the degas process is started
using the
Start
button on the Start Degas window. This option is more convenient for samples that
have specific degas requirements that should be associated with the sample file when it is created.
