Description
The FlowPrep applies both heat and a stream of inert gas to the
sample to remove adsorbed contaminants from the surface and pores
in preparation for analysis for up to six samples. Choose the tem-
perature, gas, and flow rate best suited for your sample material. The
FlowPrep is an independent unit and not controlled by the analyzer.
The Smart VacPrep prepares samples by heating and evacuation. It
contains six sample ports in which up to five temperatures, ramp
rates, and soak times per sample are individually controlled by the
analyzer program so that all degas information is integrated into the
sample data file for future reference. Samples can also be prepared,
started, and completed independently. There is no need to wait for
samples on other ports to finish. Front panel buttons allow a
QuickStart operation with preprogrammed conditions.
Up to three additional Smart VacPrep degassers can be connected to
one computer permitting 24 preparation ports to be used. The Smart
VacPrep is the recommended degassing unit.
The VacPrep offers two methods for removing contaminants. In addi-
tion to flowing gas, it provides vacuum to prepare samples by heating
and evacuation of up to six samples. This combination provides pre-
paration method options best suited to your material or application.
Needle valves are also provided for introducing the vacuum slowly to
prevent fluidization of samples. The VacPrep is an independent unit
and not controlled by the analyzer.
