Slowly but surely making my way through the relative hands-on novelty of LC-IRMS analysis using Thermo's ISOLINK.  Latest spanner in the works is that both Water and Oxygen are off scale once open split is engaged and the purge valve is green.  Id rather tackle the possible solution methodically so if anyone can suggest obvious places to start Id appreciate it.  Flow rates on Surveyor and Acid/Ox pumps are acceptable, reactor is at 99.9, no visible internal damage to nafions and separation unit.
