Is there any possibilities that results from N2 physisorption are different from different machines, assuming degassing process is same? I recent had a sample tested on 2 machines, however difference of two results can be as high as 130 m2 g-1.
Dear Yujing Liu,
I suggest you to see links i hope that are on subject.
