EGAS THE AMPLE
If using the Smart VacPrep degasser, go to Smart VacPrep > Unit [n] >
Start Degas, then degas the sample using menu commands and
information entered on the Degas Conditions tab. The Smart VacPrep
Operator Manual can be found on the Micromeritics web page
(www.Micromeritics.com).
After the sample has been weighed, use a degassing unit to remove any contaminants which may
have adsorbed to the surface or pores. Appropriate degassing units are available from
Micromeritics.
After degassing is complete, perform the following steps:
1. Weigh the sample tube set containing the sample. Record the mass on the
Worksheet for Gas Adsorption on page E - 2
(After Degas).
2. Subtract the Mass of empty sample tube set (Before Degas) from the Mass of Sample tube
set plus sample (After Degas) to obtain the sample's mass. Record this value as Mass of
sample (After Degas).
