Hello Ravi,
I saw that you also asked a question about cis-platin. Are the samples you’re
trying to spin in your 2.5mm MAS platinum containing compounds? If the density of
the compounds is very high you may have greater difficulty spinning.
You might want to try the drive cap/ends which have a longer portion inside
of the rotor to constrict the sample to centre-most part of the rotor.
Cheers,
Pedro
