NMR uses thin (5mm diameter) glass tubes for samples. A sample needs to be liquid. Special solvents are often used to prepare a sample, but, direct analysis is possible. No harm in trying and seeing what happens.

No harm in trying and seeing what happens. Advanced techniques might involved solvent suppression pulse sequences or deuterated solvents.
