Dear Friends;

We have a GEO20-20 Stable Isotope Ratio Mass Spectrometer supplied By PDZE
Europa, U.K., alongwith WES, CAPS and Manifold.
For analysis of D/H ratio in water samples, we use Pt sticks as Catalyst.
I like to know the following points :
(1) Is the sticks are reusable , for how long? ( One can use them how many
times ).
(2) What is the correct method for their reactivation ? Can you kindly
send me any published paper/technical report regarding this. Please.
(3) How one can identify the quality of Pt sticks ? Is there any change in
look or any other physical method...

Eagerly waiting for your valuable suggestions/reply.

With regards,

JANI
