Dear list members,

We are in the process of setting up a CF-IRMS system (Delta + XP, gas bench,
TC-EA and flash EA) in our laboratory. We are somewhat uncertain as to the
best design for the CO gas suppyling system, in terms of efficiency and
security.

If you have gone through this as well, we would like to hear about your
choices in terms of storage of CO tank (inside, outside, security
locker....), as well as tubing, vannes and purging system for the gas
delivery line. We presently have a quotation from a major gas supplier which
is outrageously expensive and we are looking for less costy, but fully
secure, alternatives.

Please, reply directly to me at [log in to unmask]
