Dear Peter,

I just have got your message about Sr87/86 analysis, I have been out of the
lab for 2 weeks.
We can do Sr87/86 analysis also as the other stable isotopes and
radiocarbon dating as we did it for you before. You can find more info on
our web site www.geochronlabs.com.
Unfortunately we do not do helium isotopes.
You can write directly to me [log in to unmask]

Best regards,
