Anybody have alternate suppliers for the 998 alumina tubes for the TC/EA (the 47 cm length), besides Vesuvius-McDanel? I've been dealing with them for over 20 years, and they have unfortunately gotten too big for little people like myself to have satisfactory
business dealings with. I would like to try someone else.

There was a recent discussion on some complications in dealing with nitrates that you might want to look at for good measure (search the archives for the latest subject heading IAEA-N-3).
I can't imagine dicyandiamide posing problems provided enough O2, but is there any reason to measure the K3PO4 for C/N? Or are you looking at the oxygen isotopes of the PO4?

We are analysing samples (C and N of fish and invertebrates) from a controlled study where NaNO3, Kh2PO4 and dicyandiamide (C2H2N4) were added as different treatments. We are thinking of analysing the actual chemicals added to the systems to get ‘baseline’
values for each treatment. We haven’t run these in the past and would like to hear from someone who has before subjecting our instruments to weird and unusal chemicals. If anyone has experience analyzing these chemicals or can think of any potential issues
when doing so please let me know.
