Hi Purush,
have you attempted to ask around chemical etc. companies in your vicinity
whether they might have some samples to fill the weekend (hoping you're
having some type of autosampler allowing to run some stuff overnight/over
the weekend)…? You might attract some cherished third-party money
in the process while keeping the NMR busy ;-)
Cheers
Bert
