Hi All,
I have a nucleic acid based application that is incredibly sensitive to even trace (ppb) levels of sodium (and other metals) in the eluents. We currently use formic or acetic acid to flush our LCs (normal or bioinert 1260) and MSs (6130 or 6135…
This is absolutely the wrong column. Ammonia and H2S need apolar thick films to be separated and no specialized Free-Fatty-Acid-Phase (FFAP). A CP-Volamines column would do (CP7448) . Ammonia elutes just after CO2 and before water, H2S after water at…
Hello SeanPath ,
There is an example in this discussion that shows how to vary the LOQ text.

A tiny bit of fluff on the HED or the hard wire that goes from the HED feedthrough to the HED can dance with -10,000 V on it. The first easy thing to try is to vent, turn off, remove the two front cables that go to the analyzer, open the analyzer door…
I asked this same question to the Agilent tech who was here for our quarterly maintenance. You won't find any documentation and they won't give you any. Apparently, you can brick your instrument if you don't know what you're doing. The scripts are more…
Hi,
you should set your instrument to "user tune" in startup. But plasma correction is intended for a regualr setup. you can try to run it with your "special configuration".
Under "Startup Configuration" change the Ignition Sequence to "user tune…
This is the correct Tune Solution. It should be fine if you dilute it 1:10.
From the information i have, i cannot say why the res/axis is failing.
Best Regards Chris
