In our laboratory we have IRMS Delta Plus XP coupled with HDOeq unit for d2H and d18O measurement in water samples.
The problem that is bothering us for quite some time is that during measurement some of the samples are skipped (measurement line is over jumped).
There is no regularity in this over jumping: it is random.
We found that short term solution is to make new methods and sequence, and we have done it several times but after some time skipping of the lines appears again.
Does anybody have any experience with this kind of problem? Any suggestions, ideas, solution?
Thank you very much!
