I am having some problems with smart ea (flash ht plus conflo iv plus delta V). Basically, either if smart ea is set @ 8000 mV for both co2 and n2 in dual measurement mode (i.e. n2 / Co2) i found that the system is not able to catch the correct dilution. In my case i do want to analyse low n samples so I weigh samples based on n content expecting a good auto dil for c.
Before each bach we set the tcd mc calib sequence and I manually verified a perfect linearity for tcd n and c and masses 28 and 44 respectively, but the system tends to dilute also notogen peaks leading to very low signals and hence poor reproducibility. Does anybody know where the system stores the tcd ms calib files?
Does anybody have already experienced and fixed this issue?
Thanks in advance
