Pt NMR

Dear All
I'm interesting to register 195Pt NMR spectra but I have not experience
with platinum.
We have a Bruker 300 Avance equipped with a 5 mm BBO probe.
I tried to observe the spectrum with a 10 mM K2PtCl6 in D2O/H2O sample.
I detected only a very small peak (1000 scans) at 11 ppm !!!
(NB: I didn't calibrate the ppm scale with platinum)

So, is my signal the real spectrum of PT(IV) ?
Perhaps,is the concentration too low ?
Does anyone know the ppm range of K2PtCl6 ?

Thank you in advance
