This degasser is used to dry (Xeri is derived from the Greek word “xeros” meaning
“dry”), samples prior to surface area and pore size analysis by gas sorption. The
XeriPrep™ can be used with a variety of Quantachrome’s gas sorption analyzers including
the Autosorb® 6 iSA™, Autosorb® iQ, Nova™ Series, Quadrasorb™, and iSorb™.

Consistent and reliable surface area and pore size analysis depend upon proper
sample preparation. This “degassing” involves the removal of surface moisture and
other contaminants by heating the sample under vacuum. The XeriPrep™ provides
the necessary accurate and consistent sample preparation required by high-throughput
physisorption analyzers.

The XeriPrep™ degasser has six preparation stations side-by-side for easy access; each
station having its own heater for independent operation – up to 350°C (662°F) is
standard, optionally up to 450°C (842°F).

The XeriPrep™ provides PC control of all six heaters with individual protocols consistent
of programmable heating ramp and times. All six stations accept three sizes of sample
cell diameters using fittings that can be adapted quickly and easily without tools. The
built in cold trap provides for efficient removal of condensables at low degassing
temperatures and for a clean and efficient vacuum at all degassing temperatures. The
standard version of the XeriPrep™ includes a two-stage vacuum pump with the option
of adding a turbo pump for rapid high vacuum degassing. Also included is a digital
vacuum gauge for establishing completeness of sample readiness after degassing.
