Paul, We analyse and then seal them back up in 1 ml glass
We do as Ty Coplen recommends and calibrate two larger water
standards but it is still nice to break open an ampule every six
months for a quick check.

We are just about to crack open our IAEA water standards and
anyone has any recommendations as to how to store them once
they are open.
I assume that a small glass bottle with screw polyethylene cap
fine. If anyone has any experience storing these standards please
Thanks in advance,
