    1. GENERAL INFORMATION Description The FlowPrep 060 Degasser prepares samples for adsorption analysis. It uses flowing gas passed over a heated sample to remove moisture and other contaminants. The degasser has six heating stations for degassing samples and six cooling stations. The desired degassing temper- ature is easily set on the temperature controller pad located on the front of the instrument.

One to two hours is typical for many samples at temperatures above 200 ºC. To determine the optimum time, select the highest safe temperature for your sample, then degas it at intervals, determining the surface area after each interval.
