Has anyone seen this happening before? It's usually only on that second standard too, our continuing verification usually works just fine, but consistently that second standard comes up just a tad too high for our acceptance criteria.
Note, I've already tried the regeneration procedure Metrohm suggests; running 10x concentrated eluent through the column then rinsing and running normal eluent again. We've also replaced the CO2 trapping column, I believe, as well as a few other prefilters in the system. If no one has any advice, that's fine, we have another column ready to go, just hoping there might be a simple fix here. Thank you!
