Yes thats correct... but why do some samples require particular rpm alone?

its a physical phenomena.Centrifuge process purely based on NP weight, gravity and centrifugal force.

go for Centrifugation at high rpm or sonication can also be done.

You can liophilize the samples to remove the water and you will get your NPs in powder form

Take the aliquots of your solution in different micro tubes and centrifuge it at 10k -12k rpm for 1 hour at 20 degree C. You pool the final pellet and lyoplize as powder for further use.
