Why I got a low surface area for graphene after bath sonication in water?

I made a graphene suspension ( 100 mg in 100 mL DI water) by sonicating synthetic graphite powder (BET surface area= 10 m2/g ) for 1 h. After the sonication, the graphite BET was 8 m2/g. I...

How can I prepare my graphene sample to measure the BET surface area?

I made a graphene suspension after sonicating synthetic graphite powder in DI water ( 100 mg graphite powder in 100 mL in DI) for 1 h. Can I oven dry it prior to the BET analysis? Thank you
