Hi
Is anyone out there using a metal strip or graphite method to fuse small (maybe 100mg or
so) amounts of rock powder without flux into a glassy bead which can then be mounted,
cut, and polished for EPMA or LA-ICP-MS analysis?
I'm hoping to convert my (t)rusty old Edwards 306 vacuum coater into such a device but
I'm trying to avoid reinventing too many wheels.
I remember seeing such a method setup at UC Davis about ten years ago but I haven't
had any luck following that one up.
We actually want to use LA-ICP-MS so it seems to us that a graphite boat setup would be
better from a contamination viewpoint than a metal strip.
Any references, tips, experiences etc would be most welcome.
cheers
