This is incomplete research, but it's better than nothing. Perhaps others can use this for hints.
In the Sunday and Wednesday FFF road shows, there were references to the spectrometer apparently being run out of specification, and with old software/firmware that may present accuracy problems.
The two slides that give hints to this are this about the software:
And this about pressures:
I don't see anything clearly matching the Ion XP software, but MassLynx seems to come from Waters.com; Waters Corp divested Micromass in 2003 to GV instruments, who appears to be the current vendor of the IsoChrom and IsoPrime devices. The IsoPrime instrument is described here.
There is news at the site about the instruments being used in doping control:
Stable Isotopes in Sports Doping (Feb 06)
Following on from GV's success in supplying IsoPrimes to Athens for the 2004 Olympics, we have received a series of orders from around the world (France, Spain, India and Korea) for instruments to be used in the identification of banned substances in sports. We think this is a reflection of the acceptance of this technique by the IOC for Olympic events. It is very likely the technique will be accepted by other sporting bodies and it will be a common feature in international and national sports events around the world.
Manuals and support information appear to require a login.
There is also an Optima family of spectrometers, apparently from Perkin-Elmer, which has a software version page that doesn't go back to 1.67-X
If I read the history right, the Optima was designed by some of the people who went on to GV through a tortured path. It is possible that LNDD has an old Optima device that has not had it's firmware updated, and some newer IsoPrime units.
Corrections and additions are welcome
