Consistent and reliable surface area results depend upon proper sample preparation procedures. In terms of BET analysis, the limiting step in rate of throughput is often sample preparation. The complete degassing of samples can often require several hours, while surface area measurements may require as little as 15 minutes.
Quantachrome manufactures several models of degassers to fulfill your sample preparation needs.
The gold-standard in sample preparation for physisorption analyzers. It provides PC control of all heating zones with individual heating ramps and times. The Built-in cold trap enable efficient removal of condensables at low degassing temperatures and for a clean vacuum. Turbo-pumped version available for rapid high-vacuum degassing.
