Hi John --
I think Yves Acremann requested this as well and it was approved. This was
a few months ago. We may actually have this stuff in -house now, if this
requestor needs it (I don't know -- we had arranged for samples to be sent,
but we should check with Yves as to whether he received them.) This is
really good stuff, from what I hear, but there is a very limited shelf-life
and it is pricey, so not worth keeping a lot on hand.
